I do agree with everything you're saying, Helgoland.
I'll grant that my perspective is very much colored by living in America, and having experienced everything from dirt poor to upper middle class life here over the last 30 years. Everything I say is my own observations and thoughts processed through near-daily discussion with all kinds of people from around the world since age 14. I've never read any of Marx's works, though his influence is surely inescapable to me simply because I've grown up in a post-Cold War culture.
I describe capitalism in a Gilded-Age fashion partially because America is regressing towards that. Culture (ways of thinking) is very much at the root of everything. The rich here have worked tirelessly to subvert the government to its own ends, while undermining its power and cultural legitimacy. As a result, welfare programs have been severely perverted, and hatred for them is very common here, even among the very poor. So I put a lot of energy into arguing in favor of them, even though I'm no fan of the government myself.
I also think that welfare and regulation happen in spite of capitalist principles. It's something that has to be fought for by demand and threat of the populace directly matched against the superior resources of the wealthy who have their power limited and would be fine (in the short term) without those things.
I'm sure you've also read enough of my writing here to realize that I try whenever possible to talk about these things in their social aspects, for example how the job model effects how people relate to the concept of work and creates the cultural misconception that people are inherently lazy.
The change that I'd personally like to see very much hinges on a dramatic shift in our cultural way of thinking, and I've always said that it will never happen without that cultural shift. As it is now, I confuse the hell out of almost anybody when I try to explain it. I believe in rejecting the concept of property, while retaining the concept of direct possession. Two very different things, but our culture isn't very good at differentiating them. In other words, the changes I would like to see to the functioning of our society hinge on our culture rejecting the idea that a person can claim ownership of anything that they don't maintain a direct personal relationship with. If somebody doesn't directly interact with something or directly depend on it for their well-being, then it's stupid to allow them to restrict access to or otherwise exert control over it. But this is definitely something that requires some deep cultural re-wiring.
I'm also a technocrat of sorts... I acknowledge that prior to mass communications, it would have been very difficult, if not impossible, to direct resources into efficiently improving (potential) quality of life without centralized control over resources. However, I think that with mass communications, it should be more efficient to manage resources in a de-centralized fashion. I've gone over my beliefs regarding this in more detail a couple times before, but I don't know who has read it that's now following this thread. I've also gone into more detail about how I think society could operate through the internet once. If I have some more time this weekend, I'll write it up again.
