They become Americans and rise to your level of comfort and compensation. By working here in the US, they increase the wealth, tax base, and culture of our country. Immigration is a good thing. Skilled immigration even more so.
The alternative is that they stay in their home country, and that country grows a tech industry that rivals the US. Those workers will work for even cheaper than in the US, putting an even wider delta on price and creating an incredible arbitrage opportunity for talent.
Much like the automotive industry, foreign competition will drive margin out of our comfortable tech industry that has enjoyed being peerless for decades.

At some point, talent won't want to come to the US anymore. That should scare you.
I say all of this as someone who wants everyone to enjoy wealth and prosperity regardless of where they live. I still want opportunity and the ability to capitalize on it to be accessible to any American that would take it. And for that to continue, we should keep growing our talent pool and increasing the scope of what we can achieve together.
