we spend more per student and have lower test scores than almost any other country in the world.
We don't spend the most per student, at least not in the public schools. I lived in Sweden for 4 years. They spend more per student and have much better results. You are correct that there are factors other than money that also contribute to a good education. Instilling a love of learning at an early age is a big part of success. And encouraging self-discipline (which is totally different from externally imposed discipline) is another important factor.
please define "fair tax rate".
As an example, a tax rate that results in the richest people having a disposable income of 30 times that of a minimum wage worker, scaled progressively from bottom to top. And a middle class that has a disposable income of about 10 times the minimum wage. In other words, I would like to see a tax rate that makes it easier to get to middle class status and harder to get super rich. I know how hard most minimum wage workers have it, and I don't think anyone works hard enough or is smart enough to get more than 30 times the reward. Especially since the wealthy could never amass or maintain their wealth without the work of those at the bottom.
I think current tax rates are too high on the middle class and too low on the rich. So I'm saying that if the minimum wage worker has $10k in disposable income, the middle class should have $100k and the richest people should have $300k. I don't believe in the myth that very high incomes encourage innovation. I think people who are really innovative do it for the enjoyment of being creative.
i think it would be fair to have a flat tax rate that everyone paid no matter income or source of income.
Well, I guess we differ on this issue.
