Illegal Immigration...

Doesn't "illegal" mean: against the law? What part of that is difficult to understand?

If we turn a blind eye to illegal immigration, doesn't that mean, among other things, that the hourly wage of unskilled labor will be forced down even farther? Perhaps that's part of the problem...

At any rate, if something is illegal, it's illegal.

And by the way, California is part of the USA. It is not part of Mexico, however wonderful and well-meaning that country is. It will not be returned to Mexico, just as we shall not be returning Louisiana to France or Alaska to Russia. Neither shall we be returning the original thirteen colonies to England. England has enough trouble with dental care, let alone assuming jurisdiction over our eastern states (though, it might be nice to give them Massachusetts).
