Again, I think you're making a fallacy. What is not being said here is that 'all black people have lower IQs than all white people'.
It's an average. There are black people with an iq of 20, there are black people with an IQ of 200. There are people of all races with this kind of variance. What's being debated is the issue of how much group iqs deviate from the average level for the entirety of humanity, and how those group differences compare with one another.
And as to the issue of those that are poorer doing worse, I think you may be approaching it in a rather reversed way; you seem to say that 'people are less intelligent because they are poor'.
I am more inclined to say 'people are less wealthy because they are less intelligent'.
It's also important not to confuse intelligence with knowledge.
You can be very smart but know nothing about classical literature, law, economics, history, psychology, art etc.
And of course, you can know many things without being terribly intelligent.
My view is that education provides knowledge, it does not provide intelligence. Intelligence is something you are born with, in my view, and your intelligence is integral to your potential to gain knowledge, which is valued by human society.
If you look at those that earn the most, they are knowledge workers; lawyers, doctors, bankers, the like.
Those that earn the least are typically those that require the least knowledge; factory workers, those on welfare, those that are in occupations with a high degree of routine and a low degree of autonomy.
My theory is that a lower intelligence means a lowered ability to gain knowledge, which means a lowered ability to gain money.
