In fairness, this is an article from Slate, aka "News For Nervous Upper-Class White People". So it shouldn't shock you that they might not stop to consider how offensive "have the kids build robots!" might be to an educator in a school system that can't even afford to maintain reasonable class sizes, much less a robotics lab.
> I'm not sure you realize just how strapped for cash most school districts 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.
