They dug deep once.
For single disasters. I suggest you go back to look at how far one-shot donations actually go.
The world you advocate is one in which society does not exist. We look out for our own and send a check once in a while to feel good about ourselves. No sustainability.
One check, even one big bunch of them, will not alter a pattern that has taken years to establish. It takes years of effort to undo patterns of poverty, violence and degradation.
The most basic needs must be met before people can even afford to think about personal betterment. It requires sustained intervention provided by people willing to be in it for the long haul.
Pay now or pay later. Education and therapy, or prison. Which do you like?
