That's not about smartness or dumbness, though. I don't think intelligence is correlated with poverty much, but poverty is additional difficulty, so they have to work harder for the same thing as someone who isn't poor.

This is contrary to the available science. IQ and earnings are strongly correlated.

One aspect is that there's at least partial causality the opposite way. While earnings are correlated with IQ, they are even more correlated with your family earnings/socioeconomic status (SES); and there are many aspects of how low SES screws up childhood development and education (on average, not necessarily for all individuals) that would result, among other things, in lower IQ test results. I.e. it's a reasonable hypothesis that the correlation implies that low intelligence makes it hard to be rich just as much as being poor prevents one from developing and applying their intelligence.

But that isn't an issue where I'm from. The lifestyle difference between people with degrees and working class is tiny since the wage gaps are so small, and then add all government aids paying for everything including school lunches, daycare, college, healthcare etc on top of that. But still people from working class households perform extremely poorly. Helping them isn't about making them smarter or unlocking new potential because that doesn't work, it is simply to make everyone live a decent life.

It still doesn't necessarily come down to intelligence. It could just as well be motivation, or laziness, or other social pressures.

There is a perfect correlation between the two

Can you point me to a reference that gives a “perfect correlation” I.e. corr(IQ, poverty) = -1.0?
