> Fifty years ago it was one of India’s poorest states
Yea that is a absolutely wrong. A state that had the highest literacy rate at independence will unsurprisingly remain at the higher end of developmental rankings..
In the 1970s Kerala was already comparable to Indian states from a human development and economic standpoint because of a strong shipbuilding and cooperative agricultural program (same with then undivided Punjab) [0] and by 1990 had developmental indicators comparable to Delhi NCR.
Instead, we should look at states that were historically more undeveloped than Kerala but are now within range of Kerala.
As such, a better rags to riches model to dig into is Tamil Nadu [1] or Haryana [2] - both were on the lower end of India's HDI rankings in 1990, and now outperform most states and lead India in GDP per Capita as well.
Himachal Pradesh [3] and Jammu Kashmir [4][5] are two others to also look at, as they are historically undeveloped agrarian Himalayan border states with laggard developmental indicators that used land reform, cooperative agribusiness, mass rural education drives, and specialized manufacturing (Pharma in Himachal, Food Processing in Jammu) to have high HDIs.
