Wow....I thought our African politicians were corrupt, but they are rank amateurs compared to yours. Shithole country indeed....
I think that's not just an Africa phenomenom. Having seen some former Eastern block countries, I realized that their corrupt politicians were so totally amateur that they do their corruption illegally and sometimes even get caught and arrested. That almost never happens in the West.
In the West, on the other hand, they do corruption by getting directorships and so on after the event. Even if there are totally obvious links between the purchases they made when they were ministers and the companies that they then go and work for there is nothing that anybody can do about it and they will even boast about it. This happens not just in the US, but also in the UK ("revolving door"). There are some good reasons such as getting company experience into government and getting government knowledge to help companies develop, but those are allowed to totally override any ideas of propriety.
In fact, Trump is a great case. Everybody knows that in his first term world leaders used to stay in Trump hotels or Mar-a-Lago in order to get access. The thing is, the law (as currently interpreted) doesn't cover that case and so he gets away with it fine. Insider trading appears to go on with stocks from people on all sides of the US house. When, in his second term, people complain that Trump's cryptocurrency is obviously a way to give him bribes, it seems all they are actually doing is providing him with advertising.
