I don't understand taking other people property is legal if they legally acquired the property in the first place. I specifically don't get how you can take Roman Abramovich, Chelsea Football Club or his yachts away without proving in court him acquiring these things broke the law. And if you do start retrospectively punishing people, why not go after someone like Bill Gates who is just an American Oligarch just doesn't get called that, but rather a billionaire. He too used all kinds of shady connections to aquaria his wealth. I get the instinctive hatred for extremely rich people and their wealth. But the one thing I've come to realize as I myself become richer, every new thing I buy atomically means I get less time to enjoy my previous possessions. We all just have 24 hours in a day. So practically all those possession of the ultra rich are often just paper deeds. There is on sum, a much greater benefit of something like a Mega Yacht to all the people that work there, worked to build it, work to maintain in, crew it, dock it in ports, and so on. He himself only probably get to use it on rare occasions. To me it seems like theft to do it. Perhaps why I'm personally opposed to it, is that a few a years back I read about a government trying to take over the teachers pensions fund in Ontario. The teachers were paying out to a private firm to invest their pensions, and the firm did so well, it was worth billions of dollars. The government running a large deficit at that time, seeing that huge sum (worth 227 Billions now) started getting wet dreams how they could take it over. They backdown. But just seeing this kind of thing is off putting. It's just thievery.
