Why should they?
Theyve literally been given free reign to do whatever they want. They could be artists etc and never be starving or they could lay around all day, knowing theyre set for life.
They could do whatever the hell they want, personally if I was that rich, Id go more into art, music etc do charity work and honestly go around the world experiencing new cultures and try help those in need.
Also I'd have enough money to do BJJ, MT, etc. Fuck being broke.
