Lewis first lays out Keynes's theories and arguments by presenting what Keynes' really said in his own words. He then discusses the theories and rebuts them. And you don't need a degree in economics to understand it. The book is quite readable.
The book is an important one because most of the world is following economic policies based on Keynesian principles. And if Lewis is right, then the prescriptions are the wrong ones. In fact, Lewis makes the case that the very policies being prescribed are the ones that created the recent crisis in the first place and have never worked in the past. For example:
- "The problems that led to the financial meltdown of 2008 were rooted in too much debt. The solution, we are told, is more debt."
- "Are artificially low interest rates cheapening the value of money and creating instability? The simple response to that would be to lower the rates further."
- "If the market is not confident because of volatile spending and monetary irresponsibility, create more of both."
- "If a company is 'too big to fail,' force weakened businesses to merge making them large, weak, businesses."
