If I might ask, how long ave you been in CA?
I've been here all forty years of my life, and the state is in decline. Middle class neighborhoods are in retreat in the San Fernando Valley, as elsewhere. This proposal will be yet a further magnet for more immigrants, legal and illegal, when we haven't yet assimialted the ones we have. Meantime, underclass blacks in this state are hurt most of all, by the crowd of non-citizens at the entry rungs of the economic ladder.
My suggestions: establish a guest-worker program with teeth and severe penalties (total asset forfeiture for any violation of the law), no family reunification for non-citizens, deportation of illegals, and no welfare for anyone.
Your suggestions have no possibility of being enacted. But some sort of guest worker program is a good idea. That won't happen either, for a variety of reasons. I have lived in California my whole life, 51 years. We can discuss the state of the state another time. It is somewhat more complicated than your description. You just don't see the millions of middle class Hispanics, because they tend to be dispersed in middle class Anglo neighborhoods.
