"Money is arguably man’s greatest invention but after more than 5,000 years of trying, he has still not got it to work properly. Early man spent his entire waking life striving to feed himself but the development of agriculture enabled him to produce more than he strictly needed. The result was surplus labour that should have afforded everybody a better standard of living but the ruling classes were able to exploit this surplus through slavery and serfdom. If workers could be paid sufficient money wages to buy all of their production, then this could bring salvation. “The Trouble with Money” is that there has almost never been a sufficient circulation of money to permit this and the result is enduring unemployment and inequality."
