The issue is not electing people... it's re-election advantage. Incumbent candidates rarely lose, especially in Congress... and power is addicting. This leads to the current situation where U.S. Congress median age is pretty far on the cognitive decline curve - https://www.pewresearch.org/short-reads/2023/01/30/house-get... . I think there were multiple issues that took down USSR, but aging leadership with inflexible thinking that was not capable of keeping up with times was probably complicit in most of them.
