The odd one out in this assessment is India, because it did some similar things (land reform) without success. A difference might be that India sheltered businesses from foreign competition and didn't encourage and invest as much. Another, is that you need caste connections to do business. Culturally I intuit that the upper-castes that controlled government were less interested in rapid nationwide progress, unlike the ideologues that led South Korea and China. They lived comfortable lives and hung their hats on that.
