I just considered this yesterday. It's true that with a lot of immigrant populations the parents are somewhat expected to remain in the home and look after children and grandchildren. Sometimes it ends up that they have to go out and find work because they do not have enough money to live on. We see it quite frequently.
I think that education, such as learning English, is very important. If the immigrants who do not speak English could be urged to learn the language when they come here, I think it would be so much easier for them when they find themselves in a position such that they need to find work.
