The Hasidim and other Haredi sects can buy a house just like the rest of us do: look on Zillow, find a house in a location you like and make a bid. Nobody will discriminate against a Haredi offer. Nobody will discriminate against an African American offer.
The problem with the Hasidim and other Haredi sects is that they don't want to buy a house. They want the whole block. And it's wrong.
It's a separatist movement
The Haredim do not want to live anywhere near Americans. They avoid Gentiles, they also avoid "normal" Jews.
The Haredi culture is anathema to American culture. We believe that God created all humans as equal. The Haredim believe that God created them as superior. They (the Haredim) teach their children that their souls are superior to Gentile souls. It's all very unAmerican what goes on in that culture.
We need to understand what's going on so we can advocate for a repeal of the RLUIPA to stop this "nation within a nation" scourge.
People reading this may think: "But Jews are hard-working, intelligent people who value education and do good works."
They would be right to think that about "normal" American Jewish people who are a light unto the nations. Normal American Jewish people have given much to our nation. Many Nobel prizes, the best doctors, excellent public school teachers, great humanitarians, not to mention the awesome creative geniuses!
However the Haredim are not any of the above. They are a clannish, separatist, racist, cult.
They do not educate their children thus keeping them ignorant. They don't even teach them English. While the girls get a decent education including English, the boys barely get a 5th grade education. Many of the boys despite being born in America can not speak English. They speak Yiddish and read ancient Hebrew, spending their days pouring over ancient texts, learning no profession or trade.
The taxpayers are on the hook for providing for these able bodied men's large families.
The young men do not provide for their families and their leaders ensure that they have access to EVERY WELFARE PROGRAM available. The leaders have an organized place where the dead beat dads can sign up for every welfare program, and they do it without any shame. There is no shame in the Haredi world to mooch off the host state.
The young men do not work. The women are expected to do some work to bring in extra cash to the household (in cash or gift cards, of course to hide it from the IRS) How do the women bring in extra cash with 6 or 12 children? Playgroups. What are "playgroups." Playgroups are illegal daycare that accept CASH or giftcard payments to take care of children. They are un-licensed, un-inspected, and they pay no taxes.
Where do the women work? They work in various places within the insular community: teaching at the private school in exchange for a tuition discount, working in a Heredi store for a store credit, basically working in the underground economy to hide their earnings from the government so they can continue to mooch off the taxpayers.
The Haredim are a scourge and should be infiltrated and broken just like the mob.
Plenty of Haredim lived in mixed areas. And not all dynasties are the same.
First, the young men do not start their married life with work, but they come to it later, as I know from my own experience. Nobody over 30 does not know English, and there are Chareidi trade schools. Second, there are an awful lot of them, so they need a whole block. But upstate, new developments are blocked by locals once they discover that it’s Chareidim who are developing it. There are valid concerns that can be addressed, but outright stonewalling precludes dialogue. What’s left to do, but buy up houses. You wrote a very long post, I’m just touching on the essential points here.
I am not Chareidi, but my eldest son is. He did spend time after his first marriage studying Torah, and he also learned computers. He’s worked in a grocery store, a fish store, and now he’s marketing a phone/internet/tv package for English speakers. In everything that he’s put his hand, he’s ended up practically managing it. This is in Israel, but I’ve known plenty of Chareidim in the US, too. They are not perfect, but the picture you paint is grossly distorted.
I remember when the Satmar Chassidim moved into Far Rockaway. They built houses on an undeveloped beach facing Jamaica Bay, and moved in, bothering nobody. They were unsuccessful building the institutions they needed, such as mikveh, school and central synagogue, so they slowly trickled out, leaving the nice new houses to be bought by other ethnicities. Some have remained, and are not in any way sequestered off from their new neighbors. That, at least, is how things stood when I last visited in 2010.
As I’ve said already on multiple threads, mutual communication and negotiation is the answer, not hostile action such as you advocate, or stereotyping and slandering an entire culture without attempting to understand it.
