How do Hasidic Jews make money?

I realize that Lakewood NJ has alot of Hasidic Jews, I heard they don’t pay taxes and they have so many kids, most of the women have NJ health insurance how do they make money to survive… I always just see them walking to their synagogues.

THANKS

they don’t
they get supported by the previous generation
sucks for the next generation that’s gonna have to live in poverty
