One of the factor of production which. we are going to study is capital. The word "capital" refers to all tools, machines, buildings, and other goods which are not consumed directly for the satisfaction of the buyer, but which are used to produce or manufacture other goods and services which are consumed by the buyers. In modern civilization, the use of capital has become inevitable. Almost everything that we use is produced with the help of capital. If we destroy all capital like the railways, the motor car and other vehicles, factories, bridges and every other instrument of production, we shall become become primitive again. Capital is not an article of consumption, but without capital very few consumption goods can be produced.
