Given that wages are a function of supply and demand, and given that wages have been stagnant for Americans since the 70's, why is having tighter constraints on the supply of labor a bad thing?

Wouldn't this mean that Americans would have higher wages? Wouldn't a tight labor market incentivize investment in the growth of our own workers instead of working to maximize profits for corporations that already have historic profits by deleveraging workers?

Well, yes, based on a simple supply-and-demand model, that is what we'd expect to see. It's not what we're seeing in practice, though. We keep making immigration harder and harder, and it doesn't seem to be doing much to fix our economy -- certainly not enough to justify the real human cost.
