I kind of agree with your analysis of the system, although I kind of disagree in terms of the H&S. I mean I am from UK and they seem to have slightly more vigorous systems in place to ensure that the standards are followed than maybe in US. But US is a prime example of capitalism at its finest/worst, you decide. I personally don't like the capitalist system any more than you do, but at the end of the day - that's what people are doing so you might as well adapt the best you could to get the best you want.
Greed is the basic human emotion that everyone feels, therefore systems like this will always exist, if you want some sort of utopia maybe where everyone cares about each other and ensures that the need of human beings come first, it might be better to join an Amish community or something (Srs face here), because even the supposed socialism didn't work, millions still died as a result of the system's lack of care and it won't get any better even if the supposed communism does take effect, millions will die for the need of few, just like in capitalism.
There is no optimal system or society, it will always be like this. Adapt. As someone has pointed out before be grateful that you were born in a country that allows you to do what you want rather than in a country which constricts you and prevents your development.
It does construct your development through high school though. You're led to believe 'greatest country in the world' as if that's an actual thing and the moment you point to different reasons and facts for why that's untrue it's blah blah blah depression and blah blah blah greatest country. Every country tells itself it's the greatest. What they're really say is they believe they're better than all foreigners.
Also, how is capitalism good or even workable? There is literally an economic crash every 20 years. They call it 'downturn' but people who pay attention know what it really means. If Bush Sr. hadn't raised taxes, our economy would have tanked in the late 80s - early 90s. So really, how the hell is capitalism workable anymore?
