Imagine if US removed the RR era change that destroyed college system and allowed people to attend college & thus having many more people for these type of jobs...
While I was in the US when Ronny came into office (and my dad had to suffer the $ exchange rate going up as a consequence), neither I nor my kids had or have to pay tons of money to go to university. And we both even had the choice (not always taken) of going to a good university reachable from the family home and thus with nearly zero living expenses.
And while I suffered a childhood without computers (like Ronny, they came later), they had computers before they learned to write.
That still didn't have them follow me into IT or any engineering field.
That could be lazy, but I hated Math, too. I love technology, but they are mostly into gaming and way better at it than I.
Tech has lost a lot of appeal and trust, that as an engineer you'll be able to have a good life for life.
I blame RR for a lot of things, but pushing that on him doesn't seem as forgone a conclusion to me as it seems for you.
