I don’t think the US voter base is any more accepting of corruption than any other constituency.
Counterpoints: the US voter base re-elected Nixon (and largely wanted him to stay in office)...elected and then re-elected Reagan (despite him openly admitting to lying to the American public and exchanging guns for hostages)...elected Trump in the first place, cast more votes for Trump in 2020 than they had in 2016, and now look like they might just go ahead and put the corrupt gasbag right back in there despite the fact that he's openly corrupt, brags about it, and will likely get more corrupt in any second term.
The only thing that can save America from itself is a new socialist turn.
So there's your version of superman. Within the current political environment, I just don't see this happening without another depression or similar (so perhaps even decades more of what we currently got). I also am decidedly not someone in favor of eliminating democracy in favor of purportedly "temporary" one-party rule (that never fucking ends).
