Somebody: Of course. What is universal health care, for instance? The expansion of access to medical technology to the masses. Kerala has a robust public health infrastructure and state hospitals. Likewise, Cuba has an advanced biotechnology and pharmaceuticals sector.
The thing to remember when dealing with poor countries like the Indian state of Kerala is that vast improvements in life indicators can be achieved relatively cheaply through the institution of basic public health measures, nutrition, family planning, community clinics, and skilled attendants available for birth. But, beyond a certain point, further gains in life expectancy require rapidly increasing levels of technology.
In other words, you're not going to have even a middle income country with the health of a Japan or Sweden (that is to say, of a highly industrialized country with a state run health system as opposed to a private one like in the U.S.). Having said that, even the measures done by Kerala and Cuba require the extensive and equitable use of technology, which really is the ultimate benefit of socialism, not economic democracy and the seizure of state power, which are relatively illusory goals.
