There's a pretty substantial building boom (bubble?) going on in my community...housing and CRE. There have been a couple of articles in local media over the last year or so about the lack of skilled-trade labor (carpenters, plumbers, etc.) available to support the construction boom. This is, it should be noted, in a very conservative Southern town with a lot of loud (if narrow) anti-immigrant sentiment. I'm not trying to make a particular political point with this, just noting that where I live there is a net demand for labor in that exact category.
That may be the case but I'd rather legal citizens get these jobs over illegals. It may take time for the market to catch up but if the demand is there jobs will be filled eventually.
