We have said that thrift began with civilization: we might almost have said that thrift produced civilization.

Thrift produces capital; and capital is the conserved result of labour.

The capitalist is merely a man who does not spend all that is earned by work.
But thrift is not a natural instinct.

It is an acquired principle of conduct.

It involves self-denial--the denial of present enjoyment for future, good--the subordination of animal appetite to reason, forethought, and prudence.
