When No Building Is Allowed: Inside the Satmar Hassidic Takeover of a Small Town

Hasidic Jews pull similar "tricks" in Israel as well. They vote as a bloc and are the reason Netanyahu is in power. The vast majority don't serve in the army and get government financial aid, their contribution to the GDP is negative due to their larger families.

This has created a lot of tension with them and it's boiling over. The concern is that in a couple of decades they will be 25% of the population. They also play the racism card in Israel when confronted over their antics.

I can confirm that Conservative Mennonite and Amish groups also fit this description. Behing highly interdependent they can't just get up and move individually. They also have large families, so projections about how that might drive future change, zoming and constuction are interesting.
