That's a very interesting point, about the older generation thinking in their native tongue, and not being able to pass on a "substantial English" - therefore, the younger generation isn't even thinking in substantial English. They speculate that this deficiency leads to an inability to follow up on task completion per goals set, or to make good decisions. The insubstantial English may surely be an influence, but I submit that this is a problem for straight-up English-speaking younger (white) generations as well, who have English-speaking parents. It is not so easy anymore to meet goals and to keep house like our mothers and grandmothers did.
