Why the hell should that be Facebook's job?
The problem here is not lack of schools, lack of teachers (though they are problems, that's not the driver behind poor education), it's LACK OF PARENTING.
If you're kid is not learning because they're on Facebook (or Xbox, or the iPad, or whatever) all the time, you've FAILED as a parent. For some reason, that's accepted nowadays.
I work in schools.
I work in "elementary" schools (we don't call them that, but similar age range).
I work in private "elementary" schools.
The kids there don't learn because the teachers are infinitely better, or because the school buys a thousand iPads. They learn because they are ENCOURAGED to. They have to perform or they fall behind and, if they fall too far behind, the school will ask them to leave.
The schedule for a child is - to my state-educated mind - insanely busy and active. They are literally doing two things at once at all times and barely stop all day.
Because they are given a work ethic, and the parents have the incentive (money) to enforce that work ethic, they achieve much, much more.
