Disclaimer: Not an American.

Name me one country that wasn't founded on war and violence.

The situation with African Americans is still flawed and stratified, but has undeniably improved very significantly. Primarily in that they have equal opportunities on a federal level, although obviously social class and environment still play a big role in feasibility.

I'm not sure exactly what you mean here. There are sentiments against Hispanic immigrants, but the USA also has a very large and legitimate issue with illegal immigration. You can't blame everything on racism.

Incarceration rates are horrible for the entire country, no matter what way you put it. Blacks do have the highest rates, but whites aren't that far behind. It's not just a racial issue. I'd actually say that race is a fairly low concern here, rather the main one should be that the US penal system is fundamentally broken and frequently gamed by private prison corporations.

As for underrepresentation, equal opportunity should not be confused with equal representation. There are obstacles, but lower numbers alone should not be used to make such a conclusion.
