Socialism means taking away wealth from the successful people (the so called "rich") and distributing it among the so called "poor". All the businesses will be owned by the state and the regime will decide when you should eat, when you take a dump and when and whom you should marry. Socialism can't be implemented by democratic means and that's why we have authoritarian regimes such as the ones in Cuba and North Korea. Those who support socialism are always people who have no experience of living in a socialist country. Ask someone in Cuba or North Korea their opinion about socialism and you will be much surprised.
Well, first of all North Korea is a dictatorship, whereas Cuba is not like that, in Cuba you could take up any job you want, or you could even not work if you do not want to, the life is cheap even though not high quality, but it is nowhere near levels of North Korea, those are very very highly different levels of socialism.
Also why do people think of North Korea when they think about socialism? North Korea is nowhere near socialist at all, not even remotely close, I would understand Soviet Union which is a failed state and you could say that "socialism is bad, look at what happened to soviet union" and I would totally understand that, but North Korea? That is not even remotely close.
Plus you are mistaking communism and socialism, look at scandanavian countries, they have mcdonalds, they have private ownership, they have capitalism, but they are social democrats as well, high taxes that help the public, why not see a good example there?
I haven't seen any capitalism that successfully helped the poor people, they help the rich for sure but they always fail and starve and kill all their poor people, look at USA, look at UK, people starve and freeze to death there, look at Norway, they do not have that. All things you have listed about socialism are fake propraganda that could be proven otherwise very very very easily.
