alt Hacker NewsIt's clear you are not considering the long-term effects of labor policy. If we want a stronger domestic workforce, the answer is to incentivize Americans to develop the skills we need and to train them when they do not already have those skills. Mass importing foreign labor is not a substitute for building and investing in the domestic workforce.
Btw, this is analogous to the argument for positive discrimination:
Preferentially treat one group of people (non-white/women/Americans) even if in the short term the revealed preference of businesses is to hire a different group of people (white/men/immigrants), such that, in the long term, the first group of people can develop the necessary skills to compete with the second group.
Short term pain for long term gain.
