I have a bit of difficulty with the phrase "strengthens us". I read about the crime statistics ion California involving the illegal aliens, and that's not much strengthening. I read about the closing of some 64 hospitals in the LA Basin due to bankruptcy, and the potential closing of 24 more, and the administrators say it's due to the laws concerning emergency rooms and illegals' non-pay. I read about the amounts of money for the schools, generated by people with several kids and a $20,000/year income. Schools cost some $5,000 and more, per kid, per year.
When it's all added up, I see a lot of weakening. I always figured that when I lose money, I get poorer, not richer. Same for a country, seems like to me.
The situation in Texas varies only in degree, not kind, from California. Same for Arizona, per their newspaper articles; "only" $1 billion per year.
That doesn't even count the money sent out of the US and not invested here: $40 billion per year to Mexico; dunno about others.
