Interesting.
One thing that the article does not take into effect is that in 1964 there was not a glut of cheap made Chinese tools on the market. when the cheap Chinese tools were easily available, Craftsman had to cut prices to be more competitive. and that price decrease meant cheaper made tools.
I have my Grandpa's Craftsman tool set that my Dad bought him for Christmas before my Dad went into the Army in 1965. if you compare those tools to a similar modern day Craftsman equivalent, the quality difference is huge.
So I do believe that without the globalization that has occured in the past 50 years, Craftsman tools would probably still be a fairly high quality tool, and much closer to the projected prices than today's equivalent.
