A thief can be rehabilitated, a murderer can be rehabilitated, those people hurt others by the ones and tens and maybe even hundreds. A billionaire commits crimes on a scale that rivals war.

The story in OPs post is surprisingly accurate and the man did have 40B USD from bribes and other illegal business. Give the population (3M) and average income (17K USD) of Haikou he stole the equivalent of more than a year's wages from all 3 million residence. There is no way he was ignorant of the scale of his crime and there is no way to ever make him feel the 3 million working years of value that he stole from the people.

There is no rehabilitation there, punishment as a deterrent to other industrial scale criminals is all that can happen.
