The US does not have much corruption. It is present, obviously, but you probably don't realize what corruption is like in "real" 3rd world countries.
About the infrastructure, the one in the US is comparable to that of most rich countries. If you cherry-pick, sure you are going to find something.
Health care in the US is problematic but I think the best indicator of quality is life expectancy, and the US is high tier.
And you think journalists are persecuted? The US is one of the most free country in that regard, more than Europe and much more than in Asia. In "real" 3rd world countries, they get killed, tortured, and all sorts of fun things if they disagree with the local ruler.
Climbing the social ladder is far from impossible in the US. It is hard, but it is hard everywhere, the ones on top of the ladder never want to let go, but at least, in the US, there is no rule officially preventing it like castes in India.
Worker protection could be better but it is no nonexistent either. At least, there are contracts that mean something, safety standards, etc...
Incarceration rate is not necessarily the sign of a third world country. In the worst places, there are no prisons to keep criminals locked in, and they are out to get you.
