I honestly don’t know what you’re talking about or what your point is.

Rural people are poorly educated relative to suburban or urban peers. They’re also economically worse off. They also come from places that are culturally more hostile to education. They also live in places with fewer jobs that require skills learned in college.

These are all “walls” leading to lower rates of college attendance for rural kids.

Also worth noting that the vast majority of college students leave their communities to go to college. That is not at all unique to rural communities. In fact, colleges end up being the good employer in many rural communities and act as economic drivers.

The problems is often these schools are too good for the locals, or too expensive, so they don’t attend at high rates at all.
