Political Memes

I'll break this down sentence by sentence.

-According to all data we have, the living standard in developed countries is higher than in developing countries. Additionally, Capitalism is less democratic than Socialism, as Capitalism is a market of competing mini-dictators, rather than democratically run industry.

-Social Democracies a la the Nordic Countries ruthlessly exploit the third world and see rising disparity as Capitalists erode social safety nets. Mass Unionization slows this process, but Social Democracies serve as a good example of why living standards are higher when Workers have more control, and why Unionization alone isn't enough, Capitalism itself remains the problem.

-The USSR is not the only form of Socialism, and additionally it collapsed after it liberalized. It wasn't a Communist state either, as it never achieved Communism, ie it was not a Stateless, Classless, Moneyless society.

All in all, very flawed takes on your part. Attributing quality of life to Capitalism, when it was due to development, is false. Additionally, you falsely assume development only comes from Capitalism, which relies on the absurd logic that believes humans are incapable of developing democratically, and goes against this very website itself.
