I don't think it's accurate to blame Venezuela's issues entirely on over-reliance on oil. Many middle eastern countries have no other significant revenue and they're thriving. Of course, it's possible that those running Venezuela were not only corrupt, but utterly incompetent. I think only one of those descriptions applies to the middle eastern countries.
Regarding China and Russia, just imagine the types of booming economies they would have if they combined capitalism with freedom! China will likely end up dwarfing our economy anyway. I've long felt that we would eventually become a second rate power to them, much as the UK has become a second rate power to us now. Nothing particularly shameful about that, imo. But it's just not in the American DNA to be in second place, thankfully.
I don't know why you have to go down the health care rabbit hole, since we're not likely to agree, and it seems like a non-sequitur, subject-wise. Do you believe it's a right? I do not, since nobody has a right to the goods or services of others. If we could afford it, yes. But our free-spending politicians have pretty much put that idealistic dream out of reach with their greedy pork barrel spending. Given the current political climate with Dems pushing through multi-trillion dollar spending programs, just how far into debt do you think we should go? If your answer is to raise more taxes, that won't do. The golden goose will only lay so many eggs. Eventually, even well intended but naïve liberal spenders like you will have to realize we cannot sustain our current, and definitely our imminent deficit spending.
Regarding your comment about giving power to the workers, aside from how disgustingly that reeks of socialism (or the failed promise of communism) all I have to say is, stop being a worker if you don't like the existing setup. Or, at the very least, work within the system to make it better. No, I don't like it when a company stomps on an individual. But I also have to say that the individual doesn't have to let themselves get stomped on. They should quit whining, and develop another stream of revenue, IF they feel that strongly about it.
We actually have that freedom.
I've done that, and it was at a time when I had practically nothing other than serious debt, so I know it can be done.
