Many make money selling education because the demand for earning income has never gone away.

0:00Global education right now is 10 trillion. US education is 1.5 trillion. Formal education is 850 billion. So, that's 4-year degrees and 2-year degrees. Formal education in the US is declining at 6% a year in terms of enrollment rates. So, high school seniors are not enrolling as much in 2 and 4-year degrees. They're choosing alternative career paths. But, I'm putting that on a parallel track. Online education and e-learning is currently 200 billion dollars a year and is growing at 20% per year. Fast. If you take the 6% that formal education is losing, it's about 50 billion dollars a year that's going down. If you take the 20% of 200, it's 40 billion dollars a year. That one's going up. And so, the demand for education, in my opinion, has remained stagnant. People want skills to become contributing members of society and make money. Where they're choosing to spend those dollars is shifting.
