if you only consider white people the US compares much more favorably to European countries

But if you compare only white people your statistic is meaningless. For example, by focusing on white people you (on average) focus on the people that are more well-off financially.

The US is so far behind on education because the US has a lot of poor people. Which is easy to explain as poor people can't focus on education as much because they have survival on their mind all the time.

I'm sure it will become easier to educate people if they no longer need to struggle and fight to survive, so it's best to start with addressing the gross inequality. With that, crime levels will go down as well.
