Part of the problem is that you lump all those things with being observant, but they aren’t really.
A Yeshiva education is a luxury. Homeschooling is very cheap and you can hire someone for a few hours a week to supplement what you can’t.
With rare exception, you don’t NEED meat and chicken. You can have a small piece l’kavod shabbos and that’s it.
You can live further out from the Jewish community as long as its walkable. Its not convenient and hard to live outside an eruv, but its doable.
The problem is frum Jews today want it all and haven’t figured out how they are going to pay for it. Instead they just rely on the rich Jews to cover the balance.
