Without whites there would be no USA.
Without blacks there would be no United States. The entire wealth of the Colonial South was built on the backs of slaves. Without the genocide I’d native Americans there would be no United States and without Hispanics there would be no Texas and no California.
Not coincidentally, I think, the three most diverse states California, Texas and New York, are also the wealthiest. California and Texas being the most Hispanic. California also has a lot of Asians.
Without blacks and browns holding us back the US would be in a much better state.
Would it? It seems more like without you holding back the non-white races, keeping them in their place, you would all be doing better.
It takes a lot of money and energy to subjugate and incarcerate vast swaths of your population. Imagine if all that talent, energy and money was spent in lifting others up.
You might have a better, kinder, gentler nation.
