I can recommend this post by Stephen Hinton on his blog: explain the economy to me like I’m a 5-year old. And he makes it into a tale of the goodies and the baddies!
Hi IIPSTEVE. Actually MMT gives us a clue. There are 1600 working hours a year, and there should be a minimum wage per hour. So Economic Science seems to be based on LABOUR ( maybe not how Marx meant) but without labour the whole economic system would not work. The companies selling goods and services need people to earn money to be able to buy the services.
