Yeah, the old lottery for education scam. It goes into the same "lock box" that your Social Security TAX goes into.
Regarding teacher salaries, for literally my entire conscious life I've heard the whining about how underpaid they are. Well education majors in college are statistically among the very dumbest and with the weakest entry scores. When they get into the teaching profession they're very difficult to get rid of for incompetence. In some places, like NYC, getting rid of one is so close to impossible that it's easier and cheaper to just assign them to the so-called "rubber rooms" where they continue to be paid but have nothing to do.
The USA spend more per capita on primary and secondary public education than almost any country in the world. We spend more per capita than they do in countries like Finland, Germany, etc, and those countries' students run circles around ours. If a private charity had so little of every dollar actually reach the end goal, it would be illegal. The never ending sob story that demands we keep shoveling money into the gaping maw of public education is more about funneling money to unions (and by extension the Democrat Party), and maintaining sinecure for useless administrative apparatchiks, than it has ever been about making little Johnny and Susie into competent, self-sufficient adults.
