Why do people consistently get convinced by two or three news paper articles that someone is good because the report is good? You cannot become leader of a corrupt organisation without being corrupt yourself. There's simply not enough wiggle room at the top, where everybody wants to get to. He is probably not the least corrupt but the best at being corrupt without being discovered.

And if you see how he leads this "war" that the article is about you can see he has the skills. The reason he's not living in luxury may be something like that he loves power more than money.
