"claiming that public education doesn't work when there is zero evidence of that."
No evidence? The only subject where USA students excel is in "self esteem". There's plenty of evidence that public schools are failing. If they were doing well, we wouldn't continuously be talking about how to fix them.
"Donating that 100 billion to our existing education system"
LOL Right, because the problem with public schools is lack of funding.
" ... a change that shifts education into a business, where profit is the only thing that matters and the quality of education has no consideration."
You think there is a negative correlation between quality and profits? Quite the opposite. The person or business which figures out how to provide a quality education at an affordable cost will reap the profits With "quality" being in the eyes of the parents and students, not some government bureaucrat.
Nor is a profit-driven education system some malicious conspiracy against the poor. If absolutely necessary, you can take a small fraction of the hundreds of billions of dollars wasted in public schools and create an "education stamps" program.
The top-down, big government, cookie-cutter approach to education is a failure. Time to unleash the power and creativity of the free market. Give people real choices and let people who want to be in education an opportunity to figure out what works.
Wal Mart or McDonalds could run the public school system better than the government and at lower cost.
