While doing some research on “Modern Monetary Theory”, which it would seem is now just short of 30 years old, I started to look for the breakout white paper. It is available on Amazon, of course, for free if you are a user of Kindle Unlimited (about £100 p.a. ) but about £20 as a book or Kindle. Why? The marginal cost of the e-book is close to zero, and I paid a 99p transaction charge for a kindle priced at zero the other day. The high cost of the e-books is to add value to the Kindle Unlimited offer! And this is probably On top of Prime as well and they get to know what you’re researching or otherwise reading!
