The people today are greedy and selfish because in ancient times people did not value money more. They valued values. But in today's world people value money more than anything else, even their families. The people think that with money they can buy anything but with goddess they can't buy or get anything. So they can do anything to earn money. The money they have, the more they are richer. And if they are rich they can buy anything. So they are greedy and selfish.
