I know reading before commenting is anti-slashdot, but just as a point of clarification, I didn't say that they don't have enough money to solve any problems. And I wasn't setting up a strawman. I was reacting to the author cited in the summary who said:
"What they seek to leave behind is a planet burning and flooding and full of the kind of small and ordinary suffering such fortunes could alleviate in an instant."
You can't solve world poverty in an instant, no matter how much money you have. Your own links show that.
You can't solve homelessness in an instant either. In the most naive interpretation of homelessness you could solve it in a relatively short time by giving all homeless people houses. But do you truly think that solves the "problem" of homelessness? These are issues that are far deeper than a simple lack of money, or lack of housing or lack of work, and they can't be solved instantly with a single check no matter how large it is.
Sometimes you don't have to resort to a strawman argument. Sometimes the person on the other end is truly that dumb.
