Some people, regardless of race, have lower intellectual capacity. That is what IQ tests try to measure, but fail to do completely because a lot is still based on education and experience that is difficult to factor out of the tests.

A greater number of those people that have less intellectual capacity are not going to be as financially successful. Unless you just make them. And that "making" them is as temporary as the funds that keep going to them. That is NOT to say that we should not feed the poor and hungry. We should! And, we should try to educate them more, because they need more help. However, that is charity. People deserve love, food, and shelter. But, we are not able to "bring up" people to a level that cannot be sustained because they don't have the intellectual capacity. That is why welfare fails and is taken advantage of. Unless you have some sort of medicine or medical treatment that can make people with less intellectual capacity have greater intellectual capacity to even everyone out, then it should be considered charity to help the poor- not some sort of way to make everyone smarter.

Relatives purchased tickets for a show for me and my son to go to featuring fighting robots. He was extremely stimulated by it, not surprisingly, and I so want to capture that enthusiasm towards some engineering (make a robot).

Without the wealthier relatives that stimulation wouldn't have been there. Without wealthier parents he's not going to (in short term at least) have access to resources to develop towards the potential educational outcomes from that experience.

Taking a world view we must be in the top reaches of wealth too I'd imagine. Sad.
