True, but the USA has institutionalized the power of money in politics to the point that this is now a reality: what would be called outright bribery elsewhere is called campaign donations, there are lobbyists who get to write the laws that favor their paymasters and in fact it has been argued that 'money is speech' (it doesn't get much more bizarre than that to me). What Musk did during the last elections would get you jail in some 3rd world countries, you know, where they take voting serious.

Whether any of these require incredible levels of wealth or not is moot, I think. The reason for that is that it only matters when 'lesser levels of wealth' come up against 'greater levels of wealth' and the latter will always win that confrontation.
