It is the crown jewel of productivity. Private ownership of property and chattels is a hallmark of our system. Accumulation of wealth is a by product. Competition dictates that there are winners, and losers. The winners expand and create more capital.
More capital investment means more jobs.
The process is synergistic and conceived to work with minimal governmental interference. When wealth is accumulated, the assault begins on the part of the those whose only hope of acquiring wealth is to take it from the producer. To a capitalist, morality involves playing the game fairly, but playing to win. Also, the government must require the winner to hire people from the losing team. Advocacy for the under class is the rallying cry of liberals.
