Kerala owing its ‘success’ to communism/socialism is a fucking terrible example. Unless you’re using it as an example of the post hoc ergo propter hoc fallacy. The state owes most of its high social indicators to a head start over other Indian states, and, ironically, private property. This head start was provided by enlightened monarchs(the Travancore family) who encouraged land ownership by peasants and several resulting reform movements(Narayana Guru et al), meant by the time the British left India, indeed by the time socialism was even invented, Kerala already had among the richest peasants and most advanced social structures anywhere in India. In fact, the post-independence turn to communist parties (which btw later alternated quite frequently with India’s big tent party - Congress) meant that it became much more difficult for private enterprise to flourish there, and resulted in a huge displacement of Keralites. The Keralite diaspora is famous and respected throughout India(and also widespread in the middle-eastern oil economies) - but I think it’s a shame that so many of these educated, healthy people were driven from their home state by an ideology that actively hampers economic growth. For a long time, much of Kerala’s economy ran on remittances sent by the diaspora, and things are only now changing.
