On someone’s advice, I just skimmed the first 2/3 of his book on his data collection. Even his critics mostly acknowledge that his professional lifetime work on data collection is high quality. I carefully read the latter part of the book on his conclusions and I generally agree with him, partially because it passes my ‘common sense filter’ and partly because I am skeptical of mainstream economists. A little off topic, but reading the mises.org material in 2006 convinced me to temporarily get out of the stock market so my skepticism of mainstream economics at least paid off that one time.
