Although The U.S. Department of Education did not directly author the Common Core State Standards，it played a significant role in their development and promotion:

• Funding: The Department provided funding to states that adopted the Common Core through the Race to the Top program. This incentivized states to adopt the standards.

• Promotion: The Department promoted the Common Core as a way to improve education quality and prepare students for college and careers.

学生如果选择公校，那voucher的钱就给公校了啊。bottom line是鼓励学校好好办学，吸引学生来。

可以看看thomas sowell的书。作为一个黑人非常推崇charter school，他通过大量数据说明政府给公校的钱没有办法提高教育质量。而即便是在最烂的黑人区了开设的charter school都可以帮到学生提高分数，从而改变学生的命运。
