Hazlitt destroying Keynes’ General Theory (with a few mistakes)

I doubt many people would read Hazlitt’s book “The Failure of the New Economics” in full, so I put in bold all the important stuff there is to find in Hazlitt’s book in this page.

Generally, the book is great and he made several valid criticisms, some of them devastating. Although a few times, Hazlitt seems to be misreading and misinterpreting Keynes (eg, on his zero marginal efficiency of capital or his supposed socialization of investment) which is quite embarassing for Hazlitt (but only people who actually read Keynes book would agree with).
