It is not technical at all. But it is more dense than a typical non-fiction book you read these days. Also heavily referenced like a scholarly work.

I would highly recommend reading it, as it exposes you to the many biases in the orthodox framework of economic thought prevalent in the world today.

I found it to be good for casual people economic history. Wasn’t overly “economics” in the technical sense.

There are single sentences in that book that have half a dozen factual errors.

So, you decide if that is worth reading.
