Might I point out the fiat (paper) currency came about in 1916 along with the Federal Reserve. Gold and silver prices were suppressed by the central bankers to protect their theft. Trump intends to eliminate the Federal Reserve and return us to the gold standard. No more taxes too then the IRS is replaced by tariffs (ERS External Revenue Service).
Of course, most will only believe when they see it.
In general, fiat (paper) currency keeps getting inflated at an increasing rate until people will no longer accept it, then it is devalued/revalued and the cycle starts over.
Metal currencies have a similar cycle, but it is much, much longer, as slowly governments reduce the value/size of coins.
The reason we have been able to continue without a complete crash is we live in a golden age where technological advance has tended to outpace inflation of the currency.
It appears to me, President Trump is trying to overcome the inflationary acceleration through growth. With several significant and upending technological advances very close, it may work.
The ones I see are: Nuclear fusion, cheap cost to orbit, autonomous vehicles, doubling of battery energy density at roughly the same cost, and plausibly, Artificial intelligence.
Nuclear fusion - at least five companies have billion dollar plus programs to have a pilot plant in operation within the next 10 years.
Cheap cost to orbit. Musk and SpaceX have already reduced cost to orbit by 80% and expect to reduce it another 80% in the next decade.
Autonomous vehicles: Waymo in operation in some cities. Tesla expects to start this year, almost certain within three years.
Battery energy density/cost: Several technologies being pursued. Donut Lab claims bold advances, all possible, they claim they will be marketed in Verge Motorcycles this quarter (next three months). We will see.
Artifical Intelligence: has been hyped so much I do not need to discuss it. Could add humanoid robots to this, perhaps.
