ABSTRACT
While Watt and Arkwright were inventing new machines and improving them there was a loss of" exchange value" but eventually these pioneers enormously increased the productive power not only of England but of the whole world. Most inventors and those who advance technical knowledge sacrifice their savings but the national economy is immensely strengthened. Countries, such as the United States of America, have suffered huge economic losses to achieve political independence but their sacrifices have ultimately been rewarded by an immense increase in their prosperity and productive power.
