Both basically owned by foreign powers, though, you could say capitalists make better imperialists.
I'm not sure how West Germany was "owned," as opposed to East Germany and other Soviet satellite states. It certainly isn't "owned" now. Unlike North Korea, which, if not for China, might have collapsed by now.
More than 100, and the capitalism of when it started isn't the capitalism of today.
Marx was writing in the Victoria Era. If you were to speak to the ghost of Karl Marx and explain modern unions, minimum wage, Workplace Safety laws, state run schools and the like, he might think his side won. And then go to the pub and see if ghosts can drink cause he was like that.
To make it clear, everything you describe above isn't what I'd call socialism. As in, it's social welfare/social systems, but you couldn't describe the society in of itself as being socialist.
For instance, speaking personally - I enjoy the benefits of Medicare (basically free healthcare, sans an obligatory tax deposit), and work in local government, and have enjoyed the benefits of a union this year when they helped us stay employed. All of these things are great. Unfetted capitalism would be a nightmare to live in. But that doesn't make me a denizen of a socialist nation, because I'm still living in a nation (and world) where there's plenty of free enterprise. I find the aversion in the US to these things bizzare, since Republicans will yell "socialism" as a cop-out from stuff from raising the minimum wage to Medicare for All, and everything else. On the other hand, I only have to look at the history of the 20th century, and in some current countries, to realize that 'pure socialism' isn't appealing either.
I mean, I don't need to look to the past. I'm living in a country with socialised healthcare which is far more functional than the US system. And across the pond (in the other direction) are quite a few countries with nationalised utilities, high safety nets, strong unionisation, worker involvement in industry, etc.
Okay, and that's great, but you wouldn't really call the UK or any European country a socialist country, would you?
Again, everything you describe, I enjoy in Australia as well, to some extent or another. The country itself still isn't socialist. Most countries have some form of mixed economy, but for better or worse, capitalism is the world's dominant economic system. Social welfare doesn't change that.
