They have, at least in some places. Where I live (Austin TX) I've been in multiple high schools that have extensive Manual machine shop/3d printing/CNC/Electronics/etc labs for students to use. It might even be at the point where the nicest/most complete machine shops in town are actually in the suburban high schools. Go to the local FIRST https://www.firstinspires.org/ competition and talk to the kids from the high schools in the more expensive parts of town where their parents are getting tens of thousands of dollars in donations every year for the teams. Whether any random kid can use them is a different story, but they do 'work' if by success having both of your school's FIRST team leads go to MIT is any indication, as happened last year at the HS my kid graduated from.

So at least some of our students are being given the opportunity, and there are multiple paths to success, but maybe the largest difference is that while truly talented multi disciplinary young engineers (and I work with a few) are rare, they always have been. The real questions are probably around social issues, does giving your kid a phone remove the boredom that encourages them to tinker with stuff in the garage, is there a sweet spot of being able to afford an old car, but to poor to pay to fix it, force kids to learn hands on repair skills. Does being able to stop at radio shack/surplus/frys/metal supply/etc and browse racks of stuff on the way home from school encourage kids to build stuff to impress their friends, or is having it delivered in the mail enough. AKA, like me the other day, I stopped a microcenter to get a pedestrian computer peripheral I could have ordered from amazon, but discovered a ESP camera module that gave me 'ideas'.
