In Philosophy: Who Needs It she particularly directly ties socialism of any kind to altruism:
The socialists had a certain kind of logic on their side: if the collective sacrifice of all to all is the moral ideal, then they wanted to establish this ideal in practice, here and on this earth. The arguments that socialism would not and could not work, did not stop them: neither has altruism ever worked, but this has not caused men to stop and question it. Only reason can ask such questions…
So let us ask the question: Has socialism ever worked? The Prosperity Index measures over 100 countries on 89 economic analysis variables. The top 10 countries on this index in 2015 were Norway, Switzerland, Denmark, New Zealand, Sweden, Canada, Australia, Netherlands, Finland and Ireland. (The United States ranked 11th). What do these countries have in common? They all incorporate generous social programs with capitalist democracies. They confer generous welfare benefits through the redistribution of wealth, yet civil liberties are abundant, and there are few restrictions on the flow of capital or of labor. So it seems that countries that incorporate social programs into their socioeconomic policies do in fact thrive.
Insisting on your rights without acknowledging your responsibilities isn't freedom, it is adolescence.
