Ted Cruz is the 4th largest recipient of wall street money of all the candidates. He is not going to do anything to stop the cheap labor express. You are fooling yourself into thinking Ted Cruz will build even a mile of wall. He won’t.
What Ted Cruz will do is attempt to enforce the current immigration laws and hope a lot of the illegals self deport. Then the rest he will allow Congress to grant amnesty to. So its better than what we have now but it will still not be good. The flow of illegals will continue because donors have paid for it.
