That presumes they'd want to live in high-density housing, doesn't it? There is high density housing available with shorter commute times already at costs similar to low dessnity housing further out. Granted, it's not zero commute, but I' not sure how much difference that would make. Some people choose a lifestyle for their families that differs from what might be optimally efficient, for reasons that other's don't prioritize as highly.
