we already have a large pool of migrant workers and it seems like there isn't enough.
right now there is a lack of this 'underclass' labor for farms and other intense, low pay industries. they can't function with covid restrictions on that non-U.S. citizen migrant labor pool. So they aren't stealing jobs they doing jobs that otherwise go unfilled [1]
your comment also just writes off an entire class of people and their contributions. America is built on the skill & labor of the 'underclass' and historically there has been movement up the economic ladder.
This article and top comment points out that this economic improvement is currently lopsided against low income workers who are producing the net productivity gain for the owners/corps.
Housing shortage doesn't have anything to do with immigration. But that's a separate and worthy policy change to discuss as well.
There is a lot of research that shows current undocumented immigrants are a net benefit to the US purely economically speaking. Plenty of sources here [2]. I'm agreeing with parent comment in it would also solve our population growth & entitlement problems.
another interesting point in this artificial distinction between skill and unskilled: there is a talk on HN of tech corporations exploiting the high skilled tech migrants which you seem to advocate for.
using the really harsh immigration laws - for instance can't legally be unemployed or between jobs - to get lower than market price labor at the expense of US citizens on this board. Not as bad as holding passports but it is effective
