Most of the stereotypes our society attributes to race are actually due to economics.
I agree to an extent, although one could argue that economic conditions, at least irt African Americas, are in some part due to race. If you look at most of the races that immigrated to the US, they came here to make a better life for themselves. Irish, German, Chinese, Japanese, Hispanics, and others have largely come here with a purpose. And eventually managed to integrate themselves into American society. Africans were the only race who were brought here against their will, and I do believe that made it harder for them to integrate and prosper. They started off well behind the others. I think integration is starting to happen now, but due to many things including slavery and the Civil War, it has taken much longer than the other races.
