Ray Bradbury said this quote
“ Or maybe he means in a richer world the begging population is melting away. But no to that too. So maybe, perhaps, he means there aren't many 'human beings' left to look, see, and understand well enough for one to ask and one to give. Everyone busy, running, jumping, there's no time to study one another. But I guess that's bilge and hogwash, slop and sentiment. ”
