You're context dropping at the end. The critical context for the causation in question, is that for all races, education stepping higher coincides to substantial increases in likelihood of wealth attainment.

There are no exceptions that see a backwards regression (ie move up in education and down in wealth likelihood), which further boosts that it is very clear causation. Each step sees the average move considerably higher for all races.

No. It's correlation that's not a statistical fluke, but it's not causation. There are other potential explanations that the data doesn't rule out, such as wealth being highly inherited (i.e., rich people are begat from rich people) and wealthy children being pushed into higher tiers of education than poor people.

The existence of these other explanations show that the data is not necessarily indicative of causation.
