“How are these folks absorbed into the Israel economy? Jobs available?”
With great difficulty.
The young people are pretty easy. They go to school, go to the IDF (where they generally have an Orthodox conversion, if not maternally Jewish), then college/trade and instant productive citizen.
Older people have been a serious problem, and, generally speaking, they are the most in need of aliyah.
I suppose some have wealth. Anyway, I’m glad to see this.
