The real reason behind destroying public education

It's more than just making money on private education. It's about dumbing down public education to create workers for low-paying jobs by deflating their expectations and depressing their ambitions. In that sense it is about making more money, but to do that the rich need workers that will never challenge them or the unjust system they've created. It also makes workers under such conditions easier to manipulate, to direct them to blame others for their situation, like Mexicans or lazy freeloaders, diverting attention from the real creators of their fate.
