Is there a dearth of skilled labor for building houses?

As a "youth", I don't have any insight into this as I'm a renter for the foreseeable future, but my parents' and their friends complain about how difficult it is to get anybody to do any sort of construction / home upgrades, e.g. my parents putting in a heat pump.

Given how much the "you're a loser if you don't go to college" narrative has propelled people who may have been happy and skilled at carpentry, plumbing, electrical work, etc, into soulless corporate jobs, this seems like something that the US could take a page out of Germany or Switzerland's book, i.e. much more emphasis on non-uni career tracks starting in high school.
