thanks to "commies" you have:
8 hours working day (1st for all appeared seems in USSR), 2 free days per a week, free _good_ mass education and medicine (in some places, not in USA), mass pensions, adequate minimal wages, lesser expressed hithlerists (which were made by capitalists as from USA and Britain for war against USSR and for supression of socialistic/humanistic reforms in the world), etc. "bad" in your life.
Check how people lived before 1917 and after, what social changes were massively done in different countries, having the example of Russian socialistic revolution.
Socionics appeared thanks to "commies" too - it was developed in USSR, a place with a collectivistic/communistic culture and political ideology. When USA did a single dichotomy test and added misleaded functions for introverted types. When Jung himself would be against duality pairs as thought that as bad following to individualistic ideas taken from capitalistic/satanistic culture. As so the duality was useful for you as a person (not just to be pleasant and help in deals where you are weak) you need to _love_ that human to introject and study his traits, while love state (where you perceive interests of other human same important as own) is not compatible with individualism. Socionics had higher chance to appear and to get a popularity in collectivistic culture, and same stays until now - primitive individualistic MBTI approach is more popular outside of USSR still, when in USSR dominates Socionics and its ideas that to make your life better are important other people and your friendship relations with them, not just surface cooperations of 2 wannabe-independent individualists.
The get the most profit from a duality needs to have personally close friendship, altruistic joining with a mind and life of other human. The more of it - the better you'll feel and wiser may become, unlike with bad IR where to be personally closer more makes you to feel worse. And unlike with similar types which are boring to deal with and give much lesser in a friendship.
I'm not sure that some of people which claim themselves as communists/socialists in USA are not rejected or perverted initial ideas of communism. May be those are some different than were in USSR. But communism in its main ideas is _opposite_ to capitalistic ideology and to worst what this ideology creates to harm the life and interests of a _majority_ of people. It's individualism and the lie by which it is propaganded in capitalistic regimes are the main source of problems for the humanity and for most of people anywhere. Following to that ideology that majority is needed to be hold as weakened and hence to live worse than could, and to be able to do lesser useful by those artificial restrictions. To allow that majority more of power and keep a safety you need to indoctrinate them with atruistic love attitude too. While capitalism does the opposite - it indoctrinates fear and hate among people to keep them separated and such lesser able to protect their interests, it harms their creative abbilities to control them by a minority and such do not allow them to do more useful to make the life better. Capitalism is supported by a lie, hate, violence, terror, stupidity, etc. All that shit which harms lifes of most people is supported artificially so capitalistic regimes existed further. Only to keep some minority at higher power, a minority with psychopathic psyche which betrayed the humanity.
