Republicans and the move to privatize the schools happened.

Liberalism in the school boards and teaching is what happened.

I thought I had read somewhere that the Millennials had managed to take the US down to like 47th or something in that range .

Maybe 47th is just for important things like science , math and physics ?

Everyone knows Millennials are well below average.

No kid left behind, common core etc. You know those socialistic education policies that reward mediocrity while ignoring talent?

Liberals and their unions took control of the education system.

Don't ask them LOL.

They elected Donald Trump for POTUS, for God's sake!
