Everything is used to lower wages. Uber, waymo, doordash, LLMs, etc. all reduce wages. There is no requirement in the statute that it should not lower wages. Congress considered the tradeoff and decided that it was worth having the program. It is a minuscule number, btw. 85k per year, which given the size of the US economy should not even register anywhere in any discussions. In any case, these econ 101 discussions are beyond the scope here.
