Yes, the woman who brought the Amish education problem to my attention is Torah Bontrager, who was sexually abused by male relatives as an Amish child. She ran away from home to get an education, eventually a PhD from Columbia. Today, she's a fierce advocate for the rights of all children to receive an education.
One small detail to point out here is that (at least technically) U.S. children who are homeschooled or who receive private religious education still theoretically receive education that meets state standards. Most homeschooling parents and private schools are not exempt from state education laws and policies.
That's not to say that the education these kids receive is always up to snuff, but at least they still retain their theoretical human right to an education — unlike Amish and certain other children raised by religious parents who claim that withholding education is a fundamental part of their religious identity, and whose right to withhold education has been affirmed by the Supreme Court.
This is one of the reason that the United States is the only developed nation that has not signed on to the U.N. treaty recognizing the human rights of children. We would be unable to meet the terms of the treaty given that Supreme Court decision.
