Conventillos better than villas.
Education was as its best ever, the public school did work those days, we re talking of what demographers call "transicion demografica", which means huge infraestructure works in the cities, like agua potable, gas, cloacas, etc, with the result: the extension of life expectancy. It was an integrated society, for example, the public school, since you almost did not have private ones, was an open spot where converged the multimillionaire with the poor. And everything was like that, they were every where, every time, at the same place, social interaction, the relationship with the otherness, they took the same bus, they walk the same street, they lived under the same State (this is the key to understand what Im saying, the role of the state and its investments in infraestructure, education, health, etc) of course less corruption, less invation of the market in peoples lives (you know, the way they dressed, what they ate, no Nike or McDonalds, etc)
