Do you think billionaires should give their wealth to charity?

sometimes when I think of human society and I want to be able to visualise it I imagine a much smaller humanity, like 30 people on an island. things would have to derail seriously so that one guy would end up owning 95 percent of the ressources and then 4 people from the original 30 are now starving because of some flawed system that was ment to make sense initially but got corrupted by greedy people. we're thought that everything is ok because everyone can reach any goals with hard work and they're are no limits to how much one can own. that there are no limits to how much one can own makes no sense at all but we were fooled into thinking that its ok since we all could reach that. "the sky's the limit" 'dare to dream" etc. the reality is that these conditions are perfect for those that have the power already. the fact that there is no limit to how much we can own is very useful to the rich but almost useless to the poor but if they're been sold the american dream then even the poor will defend the right to the rich to own everything.
