in an inflationary environment it does not pay to save fiat, but most people do not realize that until to late
The issue is not 'fiat' - the issue is debt-based money.
'Fiat' currency has been used successfully for hundreds of years in many major economies. Take the tally sticks of England as but one example - before the Bank of England was established in the 1690's and brought in debt-based money.
The American colonists used colonial script with no issue - until England began harassing them to use the new debt-based issuance.
Our solution is to turn away from debt-based money and have the US Treasury issue our money supply as payment of work completed - not as the opposite side of the balance sheet backed by US debt issuance.
The last person to attempt that was JFK in his 1963 Executive Order regarding the US Treasury issuing Silver Certificates. He signed it in June. The banksters had him assassinated not long after.
The new Argentinian president has vowed to get rid of their central bank. That's the equivalent of signing one's own death warrant if he attempts to follow through.
Why? Because debt-based money is really just a claim on the promise of future labor. The holders of those claims are the masters. Those in debt simply slaves.
What does sinful man crave? The control over the labor and future actions of the rest of mankind - Power.
Billionaires don't care about how high their stack of money is - they care about power. Pure raw power. They will destroy those who get in the way of that.
