The so-called socialist economies were just the extreme form of monopolistic capitalism.
As a child, I experienced the reality of "socialism", where every word used by the ruling elites meant something very different from what it was claimed to mean.
Unfortunately, already for more than a quarter of century USA and most "capitalistic" countries every year become more and more alike to the former socialist countries, from all points of view, like great wealth inequality, markets dominated by quasi-monopolies, non-existent political opposition, mass surveillance of the population, confusing propaganda in all mass-media, less and less chances to afford to truly be the owner of many kinds of things, like houses, cars or computers. If your car or your computer or your smartphone or your TV set do whatever their vendor or the government want, instead of doing what you want, then obviously you are not their owner.
fancy way of saying "communism has never been done properly before."
yeah well that's because the execution matters and turns out when you give people power to choose who gets what, they abuse it. go figure.
