I'm really tired of hearing the argument "we're the richest country on Earth and "X" still happens!"
Of course "X" still happens. "X" is lower on our priorities list than other more pressing issues. Are diapers really the cross we're going to die on now?
We spend ~$3tn helping people every year (federal, state, and local). I think its safe to assume the "richest country on Earth" is trying.
