Earlier quoted context omitted.
There is no resource scarcity. 6 men own as much wealth as the poorest 50% of the _planet_. This is a crisis of capitalism and wealth distribution.
You can't eat money though. If they (the 6 most wealthy people) cashed in all their stock and re-distributed their wealth as best they could, the value of money would plummet since so much more is in circulation. It would crash the global economy and cause even more poverty.
That only the few can control which projects are invested in and compounded by [lack of] any semblance of "altruistic transparency" is the main concern not the wealth itself.
