It's the management of the fiat currency that's part of the problem, not the fiat currency itself. Fundamentally it's human laziness and corruptablility, both actively and passively. But it's also basic human nature in reaction to stock market bubbles and the fomo of getting rich quick. There aren't enough rules and regulation around stock market trading, or at least they're not enforced well enough, to maintain some kind of rationality. ... and it still may not actually be possible. But there's little effort to reign it in because the powers that be tend to massively profit from the status quo.
