Which is the worst culture? Is there any culture incapable of sustaining socialism...

The worst is chan culture.

What, did someone say some mean words to you and that upset your tummy wummy?
Go set yourself on fire, asshole.

American society and government not being especially free doesn't have anything to do with what he said, though
There are significant currents of general anti-government, anti-authoritarianism and reverence for liberty in american culture, what do you think the lolbertarians and other NOH STEP ON SNEK waving sorts are smoking?
Its really not hard to imagine framing american freedum values in favor of some kind of anarchism.
Though noone actually cares about those ideals except when they're out of power, hypocritical shitstains they are. Free speech is a good example, they both think that you should face "consequences" for your words when they're in power and you say something they dont like.

Socialism was sustained for a long time in many different cultures as the workers owned the means of production and very strongly when religion is involved as religious individuals like monks and nuns for millennia and to this day still live and work in communes.

That said, they were almost always less advanced than capitalism, and were generally highly simple and primitive.

One problem with socialism that a lot of theorists have yet to solve is how much it destroys motivation and ambition, seeing how there's not much point if you can't raise up to own a large chunk of private property of your own and personal rewards are low to nonexistent as they see it anyway.

This further seen in the fact that employee owned businesses and co-opts can easily exist in capitalist nations, yet they can never do well as the super capitalist entities, partially maybe because of super capitalists malicious influencing of policy but another is the nature of very large competing individual interests found in workers owning the means of production rather than just a few executives at the top.

It's a problem you can't even fix with democracy because if 100 workers can tell what 99 workers to do, there's bond to be revolution, except this time it'll be against the worker's revolution and repeat to the fall of the Roman Republic in favour of Roman Fascism, which miraculously lasted over a thousand years.

I guess it's to say, it's the age old problem of dieconomies of scale and why Rome having more than one emperor/dictator was so disastrous.

Germans are eternally classcucked. If there's one thing Antideutsche are right about, it's that Germany must die.

I agree that american culture put emphasis in THE WORD "freedom", but the word freedom doesn't mean anything. I don't agree with calling everything a spook but the americans conception of "freedom" is certainly a spook.

They believe in freedom in the sense of having low taxes, having guns, being fat, etc.

you're being far too absolutist about this, and you're wrong if you suggest a sentiment of "people shouldnt tell me what to do" and "authority should fuck off" aren't longstanding tendencies with lots of history and continued presence in american culture.
They arent completely universal everywhere and there are alot of places where and ways in which "freedom" is used totally meaninglessly and is a complete spook, this is true. But that spook comes from the "dont tell me what to do" and "authority fuck off reee" shit that goes way back and still is some part of the culture.
Don't pretend shit that is very much there isn't to prop up your criticism. I'm not even trying to say AMERICA SO GREAT MUH LIBERTY, but its blatantly unrealistic to act like there isnt any significant meme of "freedom" in america other than the spook.

Gotta be one of those Middle Eastern countries where "Honour Killings" are still in fashion.

I suppose I should add- the "muh freedum" crap is absolutely much more visible than anything else 'freedom', but big loud easily visible things that get shouted about and displayed are not, taken at face value, an accurate assessment of what a culture is like. At least, nowhere near a complete one.

The Empire never ended.

That's a lot of south slavic countries as well. It isn't that rare in Albania
