All I've got is my ex-wife's version. She was not impressed. She lived in Jerusalem. She just thought the Orthodox Jews were annoying and frankly bonkers. Everybody else thought they were cunts and did their best to distance themselves. Everybody hated the settlers. She'd grown up in the ghetto of Budapest and belonged to that temple. When she got to Israel she didn't like how religious Jewishness was forced upon new immigrants. Getting involved in Jewish religious groups gave instant access to all manner of opportunities. Most of which were financed by American Jewish money, in order to promote Jewish religious traditions. She thought it was contrived. They had to pretend to hold traditions they hadn't in Hungary just to have access to society. Jobs for instance.
OK, let's put it in order.
Orthodox jews are problematic part of the israeli society. Part of them don't recognize the state of Israel, doesn't serve in the army etc.
Yes, part of jewish immigrants have no idea about jewish traditions. In fact from orthodoxal point of view many of them are even not jews. Yes, some of immigrants came to Israel for economic reasons. But Israel is the country of the law. There is the Law of Return and it is applied. This law is not fully compliant with orthodoxical definition of jews and this is a known fact.
The wrong in your post is that getting involved in Jewish religious groups gave instant access to all manner of opportunities. Orthodox jews are less educated and have no position in real israeli economy. Most of these people have just little family businesses.
Most of immigrants from Europe, including those from former USSR, are usually well educated and don't need such perspective as poor little business. Plenty of them got good positions. The minister of forign affairs Lieberman is not only example. There are no orthodox jews in current government.
