It is a nice salary, sure. But it doesn't cover much more than regular basic expenses for a family of 10 or more.
Forget statistics for a minute,
How many frum families with children do you know who make 200k and are upper middle class?
Answer: (almost) zero
Our lives are a little more expensive, but some of that is our own doing. I live OOT, and less than 10% of the entire community makes over 150k. We're all doing fine. Nice shul, functioning school, everyone eats, everyone is dressed, and we've all got roofs over our heads. Our simchos are simple, our cars are used, maybe 4 people own a watch worth over 1k. Walking into the frum stores in NY/NJ, between clothing, silver, jewelry, and even the grocery stores, has most OOTers shaking their heads. What people have become accustomed to as "just getting by" is ridiculous.
(I don't mean to paint everyone with one broad brush. It's just that seeing how prevalent this culture is, it makes it hard to sympathize when people claim to struggle while making more than 95% of this country, which as a whole is one of the most affluent in the world. Seeing these wedding expenses doesn't help, either. )
