I believe your number is a wee bit high there. I can send my kid to a full year of COLLEGE for that amount.
Further more, I paid school district tax long before my children were enrolled and am still paying it long after they have graduated.
Next point. The FEDERAL government has no business butting in to how we educate our children at the LOCAL level. I know people on the school board and we are quite capable of running our schools without Michelle Obama's edicts. So your "have it both ways" argument does not hold.
