My parents are probably 20 years from dying. When they die I expect them to leave me with roughly 100K. By then I won't even care about the money hopefully, and it will get passed down to my children when I die old.

Anyway, I have worked in some very poor areas, and I can tell you that even some children of first-gen immigrants are spoiled brats (not as a rule, but there are some). I don't know if generational wealth makes it more or less likely. Has more to do with the principles that the parents believe in and live day to day. You can have a nice house, drive a nice car, and still not give your child a handout and make them get a job.
