I'm not sure you realize just how strapped for cash most school districts are. The average K-12 teacher in the US spends around $350 out of their own pocket each year just to buy supplies like books, pencils and glue that schools and parents can't or won't pay for. Only 8% of teachers can get through a year without spending any of their own money on supplies.

If school districts can't afford to buy pencils, it's unlikely they can afford to buy robots, no matter how cheap the robots are.

They're actually not that cash-strapped. They just don't choose to spend money on education.

It's unclear how giving them more money will change that.

Seriously - take the spending per-pupil year and multiply it by the number of kids in a class room. Subtract the teacher's salary and benefits. Subtract the cost of the room and educational facilities (like the library). Heck - subtract the cost of the playground.

Now, ask yourself where the rest of the money went.
