The US also sees a huge amount of wealth directly or indirectly flowing through it. I would say that’s the attraction for illegal activities, less the amount of people.
And I don’t know how small you think the list is, but I suspect it’s quite small because whether you get prosecuted from some corrupt act is pretty random since someone has to notice the corruption and try to investigate. Additionally the recent moves by SCOTUS is to significantly raise the bar for prosecuting corruption. So however you think America is fairing compared to other countries, I’d say America today is allowing once more, more institutionalized corruption than it had in the second half of the 20th century (and America’s history is filled with top-to-bottom corruption).
