Yes, and we've established that these people exist - aside from the info you've been presented, it should be pretty clear, anecdotally, if you have spent time with communities of first generation immigrants.
For example, I grew up with close friends whose parents were Bulgarian immigrants. Their parents had "good" jobs (dba, generic in-house IT) and were not hurting from money, but: they did not purchase homes, did not invest their money, and literally kept stacks of cash in the home.
