I'm afraid that we're reaching the end of a very long road.
Unsound money ("fiat" money not backed by gold) has led, in recent decades, to huge and unsustainable global imbalances in trade and debt. But because trade deficits REDUCE our nation's GDP, persistent trade deficits in our country have led to rising debt at every level as we try to maintain the "appearance" of a rising standard of living. This is partly why the US ran $10 Trillion in government deficits in the past 10 years alone. Can you imagine what our economy would have looked like without all that money? It would have been outright Depression. (I'm not even going to mention the $4T bank reserve creation by the Federal Reserve). All of that debt is masking depression. Even so, the number of full-time jobs is barely above 2007 levels (only +3M) and "good jobs" or good-paying "breadwinner jobs" are still lower than the last peak.
Even with our still rising debt (deficit spending) in the last year, China has seen a fall in exports. World trade is flatlining or declining. Why? Because the US and Western consumers can't afford the imports! Trump is right about trade. Our economy is hollowed-out by the loss of manufacturing jobs and it has killed jobs and hurt our people. Now the US consumer is tapped-out. Furthermore, demographic trends have turned negative in most of the West and China just like Harry Dent predicted and has slowed the economy.
The persistent budget and trade imbalances over the past several decades could never have happened with "sound" money, as the deficit nation would have seen a loss of gold (money) that would have slowed the economy and reduced imports to a balance with exports. And debt creation would have been severely limited since new money would have to be backed by gold-- and gold is limited. Exchange rates would have been very stable too. That is the beauty of the gold standard. The gold standard will eventually make a return out of the ashes of the next financial/economic crisis.
Other reasons why we're reaching (or reached?) the end of the road financially and economically:
1) Rising debt in the US has hid the increasing poverty caused by the wealth transfer from US to China (and Japan before them) for awhile. But debt levels have risen everywhere and it's marginal utility to produce growth is nearly gone, even in China. Debt levels continue to rise faster than GDP (everywhere). If the world economy continues to stagnate, there is potential of corporate debt defaults especially in Emerging Market countries. Even sovereign debt is at risk, first in commodity producing countries and peripheral EU countries like Greece and Italy then the rest. Interest rates might rise at the worse possible time as a result of debt distress and defaults.
2) Zero interest rates have prolonged the game for awhile but low or zero rates are unsustainable. Pensions are already failing in many cities in the US and around the world as investment returns in bonds has dropped so low that pensions don't have enough money to pay benefits. Also, there are far too few workers per beneficiary now (see Demographics are Destiny below). The math doesn't work. Expect cuts in benefits which lower consumer income and spending. But the necessary higher interest rates would blow up the deficit here and kill the economy.
3) Trump is right, the US economy is hollowed-out with the loss of manufacturing jobs and the loss of entire industries. The non-elite workers in the US are financially tapped-out with stagnate incomes and burdened with rapidly rising costs of healthcare, healthcare insurance, rents, food, drugs. Our imports are way down. China is feeling this as their exports are way down. World trade is stagnating. The manufacturing sector in this country has been in recession for years now. General recession may be just around the corner.
4) The economy is in near-recession despite rising debt bubbles. The US government has racked up $10 Trillion in debt in just 10 years. In recent years, if you subtracted the debt racked up by the government, our nation's GDP would have been negative for much of the last 10 years. China racked-up double that amount of debt in the same timeframe. A vast expansion of US auto loans that some people say is reminiscent of another subprime bubble has propped-up the auto sector. A trillion dollars in student loans have been given to students in the past 8 years and 43% of these loans are now not being payed back.And the US is still making more of these loans!
5) Demographics are destiny. The working age population is beginning to shrink in all of the important economies. This portends shrinking demand for everything which means the end of growth for the entire world. Companies can automate, but who will they sell to?
6) The real money supply to the world, the "Eurodollar" and it's associated derivatives, has been in decay since 2011 (see HERE) and the great financial crisis. Since then, banks have been exiting these shadow banking markets at an increasing rate. Just look at bank stocks to see the decline in their trading and profits. Central bankers haven't noticed this most important development as they are willfully blind and/or incompetent . They don't know what they are doing!
7) QE doesn't work. That's obvious. Even the educated idiots at central banks can see that! They just can't admit it and it's making them look like fools. They are starting to tip-toe away from it.
8) NIRP and the risk of depositor "bail-ins" is killing the EU banking system! And NIRP and ZIRP is killing pension funds, insurance companies and retirees everywhere. The situation is completely unsustainable. Never in history have interest rates been zero or negative. It's absurd and causing more harm than good. EU banks are a systemic risk to the world. What can't be sustained, won't! The EU is likely the epicenter of the next financial crisis which may be triggered by a political crisis.
9) 30 years of declining interest rates is over. So just steady rates is a trend change. US and world rates are now rising as front-running investors can "smell" that the EU and Japan are about to get out of the QE business. Interest rates are rising now in the US; not falling.
10) EU banks are a royal mess. Chinese debt system is a royal mess. The risk of a sudden and substantial Chinese devaluation is increasing as they will surely nationalize huge amounts of bad corporate debt that they created since 2009. Already the Chinese currency is falling slowly this year and is back to 2010 levels. Even small devaluations have roiled markets recently. A sudden and substantial devaluation would set off a world-wide crash. It's possible that civil unrest may lead to social disintegration if not outright revolution at some point in China.
11) The era of cheap energy is over. If the economy tries to recover, oil prices rise so high that it kills the economy/consumers. If we can't afford high oil prices, then we cannot have growth. (because growth causes unaffordably high oil prices!) And the price at which oil is affordable, ie., $30 to $40 per barrel, kills the oil producers and oil producing countries (and kills oil export country government revenues). The cost of extraction of a "marginal" barrel of oil is much higher now. So, energy production will eventually drop and all the oil and commodity producing countries will remain in recession or depression. What's needed to "save" us is cheap, ie., $10 oil, for an extended period or a miracle in cheap energy technology.
12) The Middle East and North Africa is already in a state of collapse, setting off a disastrous migration crisis into Europe. It's going to get worse as low oil prices will collapse Saudi Arabia and the other countries that have managed to avoid chaotic crashes. That entire region will collapse.
13) If growth is dead, then the mountain of debt, which continues to accumulate at a rate much higher than nominal GDP growth worldwide, is unsustainable. The end of the road is defaults, crises, recession and depression. Debt defaults by companies and entire countries will cause a new round of banking troubles and trouble in global supply chains. It happened in 2008 after all. Collapse is a real possibility. When it happens is the $64 Trillion question.
14) Economic stagnation, if prolonged, will cause political turmoil that will eventually affect markets and economies. Witness Catalonia, the recent Austrian election, Brexit, the election of Trump, etc. There is trouble brewing even in the US as the entire government is full of liars and cretins including the deep state, who is dedicated to overthrowing Trump's election and his plan to reform the economy. This means that, even in the US, a large portion of the US govt, the deep state, is engaged in sedition and treason. The Deep State doesn't want reform!
15) The USA may now be a failed state due to stupidity, corruption, and utter and complete collapse of competence of the Fed. Govt. There is utter gridlock of political discord as the Democrats have completely lost their minds along with their constituents. Corruption under Clinton and Obama is coming to light that may put an end to the Democratic Party. Meanwhile, everything is broken and un-fixed in the nation at the same time there is a non-functioning government. There will be consequences to such chaos especially when financial and economic crises erupt (very soon).
So, we really are reaching the end of the road. We're all in for a rude awakening at some point.
