Yseribus: That isn’t a problem. That is a constitutional right. Chasidic parents have the right to choose to not secularly educate their children after eighth grade. See the U.S. Supreme Court decision in Yoder v. Wisconsin. That takes precedence over state laws, and Yoder overruled state law.
The more time spent on secular studies the less time there is available for Limud Torah, which is far more important. It is impossible to give a “public school equivalent education” PLUS a full Torah/Jewish education. There aren’t enough waking hours in a day for a child to have two such full curriculums.
Besides the fact that Yeshiva kids, even putting aside their Jewish education and knowledge, do better in secular studies than New York City public school kids.
Parents have the inherent right to choose how to educate their children. And they’re wise to choose Torah over evolution.
