I just hate it when people complain about education but have no suggestions whatever for how to fix it.
This is me raising my hand furiously...
Fixing education is easy. Get the government out of the education business.
Now, I'm not saying states shouldn't redistribute wealth in order for poor people to get an education, but the government should not RUN the schools, from determining what's in the text books to how many tater tots are served at lunch. It's an unholy alliance between local, state and federal governments that ensures there is little competition and no consequences for failing to meet the expectations of the the school's customers, parents.
The USA consistently spends more on K-12 education than just about any other country and we spend more and more every year...yet the results get worse. Any rational market wouldn't last long with that kind of inefficiency and poor performance. Only a government monopoly on affordable education gets you that kind of crappy result.
You want to fix education, end the monopoly and allow competition to thrive. There you go, fixed.
