“Like any ecosystem, a modern economy cannot survive without recycling. Just as animals and plants are continually recycling the oxygen and carbon dioxide that the other provides, so too must workers recycle their wages by spending them in shops and businesses recycle their revenues by spending them on salaries if both are to survive. And just as in our ecosystems, in which a failure of recycling leads to desertification, so when recycling breaks down in the economy we end up with a crisis that results in devastating poverty and deprivation.”
