We have those jobs here, but they aren’t available/open. The unskilled low-paying service jobs here can’t match the jobs we’ve been losing for decades; they only appeal to foreigners who were living thirty to a room in some hot toilet south of the border. An American couldn’t hope to have a family on those salaries.
Single-home constructions are basically done here; any new construction is either new self-storage units, Laundromats, or occasionally a yuppie hive (designed for people with a good job but no family). This country’s political landscape has polarized between American taxpayers (often with no genetic future/children) and foreigners (with no economic future but with families).
