Merely to curb desires and appetite in one direction is not enough if we permit them to run rife in other directions. Our primitive man when he discovered the surplus fish, might very well have refrained entirely from labor while they lasted, spending his time in sleep or in sight-seeing. We can even imagine his skimping himself in the matter of meat in order to find time to gather berries or nuts for food. Clearly, in neither case would he have created any capital. Nor should we under similar circumstances. A curtailment of expenditures in one direction may or may not contribute to an increase of capital. We must not, if we are to assist in the creation of capital, permit economy in the use of some goods to be entirely nullified by extravagances in the use of other goods. Consequently, the second step toward the creation of capital is that income must exceed outgo.
