If corporations truly had that much power, we wouldn't even have schools. The children would be in the mines or meat packing plants (which is starting to make a comeback).
This meme is bullshit anti-academic propaganda. There's a reason right-wing politicians love to defend and attack schools. They wanted schools segregated. They want vouchers for private schools. There's been a rise lately in conservative parents turning to home schooling to avoid evolution, sex ed, or the many boogymen alt-right politicians have made up.
