And some will defend them as hardworking people who worked day in and day out for their wealth.
I'm sorry, no intention to depreciate your effort or success, but if you are building a super-yatch and your employees still have to pee in bottles you are greedy scum who doesn't deserve success. There's more than enough success to distribute part of it into happy employees who like to work for you, while still leaving you nasty rich.
No one needs untold amounts of wealth, and frankly there should be a cap at "fuck you money" level. Once you can spend "fuck you money" you know damn well you don't need any more, you just need to maintain yourself there.
