Material 1: "Capital increases due to thrift; it decreases due to extravagance and presumption. The amount of income a man saves increases his capital.

If everyone tries to consume less and save more, the attempt is bound to fail because the income will be affected.

If everyone tries to consume less and save more, this attempt will fail because the income will be affected, and the attempt will be self-defeating.
