The sad thing about this "socialism" is no matter how many countries tried it and failed, people always tried to push this crap again and again. It's like a cycle: the poor want more from the rich -> coup/election -> socialism -> all become poorer -> coup/election -> capitalism -> new rich people emerge.
You always want something that you don't have.
People who ask for socialism feel that they are treated unfair from the governments so they ask for getting more money. In some capitalism countries, governments transfer money from the poor levels to the richer levels through taxation.
This is why there are still people who search for socialism, they want to tackle this unfair situation.
