I have 1 son, my DH has a son and a daughter. Son and I moved around quite a bit when he was younger, then we stayed put for quite a while. Everywhere any of us lived, there were a LOT of things for school that we paid for. Any extra activities were also extra money. We did some home schooling, as well. Now, all the kids are grown, and our taxes are still paying for education for other people's kids. That's ok, I believe kids need an education, and that it benefits society as a whole if they get it.
I think it sucks that our teachers aren't better paid, and that so many schools are under-supplied. I'm in KY, where sports appear to take precedence over science, and I think that sucks, too. I don't have anything against kids playing various sports, I'm all for physical activity. I just wish that basic education was as popular as sports programs.
