A big part of your Asian immigrant model is centered upon grandparents and relatives helping raise the children during their early years while the parents are out working.

In a second generation Asian (or in my case Indian) family, the grandparents are still working full time, they live in a different city, and there's no family owned business which can provide a flexible schedule and avoid tax/labor laws for the immigrant model to work. Parents have to step up or pay for round the clock childcare.
