Allowing individuals to hoard enough wealth to corrupt, at will, the system that gave them their wealth - maybe that wasn’t such a good idea after all.
It's not like the Soviets fared much better with regards to corruption and institutional decay, to the part where the rampant corruption of the Brezhnev-era was a major contributing cause to the eventual collapse of the union.
Institutional longevity is largely an unsolved problem. Seems having checks and balances like the US does helps slow it down to some extent, but is far from a guarantee.
