There will always exist a gap between the rich and the poor. In free nations the gap exists between those who are blessed with inheritances, higher levels of intelligence, luck in business, hard work in business, responsible behaviors and lifestyles, and so forth, and those lacking such advantages. In communist and slave nations the gap exists between the rich in power with their supporters and the slaves lacking any voice in politics.
Matthew 26:11
For ye have the poor always with you; but me ye have not always.
