In the old standard those with "money" had a death grip on it. Today's grip by the rich is barely an infant's grab in comparison. JP Morgan bailed out the US gov from his private liquidity back in the day.
Many of downfalls of today's system, which is not by faith. That's straight up flat earther level research. It's a complex system based more on import/export rates along with debt to fulfillment ratios. Take an econ 101 class or pick up a book from the library to get a better run down. Anyways, the downfalls come from early implementation problems and micro management. Micro management and mishandling can be seen in the Zimbabwe scenario. That didnt happen in a bubble. Mugabe embezzled tons of money, over taxed, did land redistribution of farms to those that didnt know how to manage the land, and implemented a pseudo command control economy. Nope, its "fiat currency's" fault. That's the equivalent of stubbing your toe and blaming an enemy religion.
Is capitalism and current money policy perfect? Hell no. But it's been the best system so far to actually even out wealth thus far. Again, not perfect (by a lot), but its opened up far better than the past systems. This demand of burn it down is just childish, flat earth level ranting. Read a 101 book on current micro and macro econ before taking hot-take cherry picked talking points as defining gospel.
