Working class to me means Walmart, Mcdonalds, and Jack Generic Construction LLC.
Working class to most people just means that they do manual labor. They work outside and in factories building and moving physical things be it burgers or buildings or balloon animals. The key seems to be that they don't generally sit at a desk with a computer on it for 8hrs a day.
A huge number of "tech workers" today are from the same families that would be working class, factory workers, and so on just a generation ago.
There's no magical racial difference between working class people and tech workers.
Let's say 10% of these working class people just need a push to discover they're actually decent at coding/devops/admin/etc. 3,500,000 truck drivers means an additional 350,000 people competing for IT jobs. Now factor in all the other people employed in these sorts of jobs. There's going to be a huge glut of incoming "cheap" labor when these sectors become more automated. I don't expect them to be competing with people like Linus but they're sure as hell going to be competing with the neighbors kid that went to a public 4 year school for a CS degree because the job prospects were good.
Well, neither do most tech workers. Why’s there another high profile breach seemingly every week? Why is software generally full of bugs? Because the devs lack basic competence at their jobs. Maybe they should have been flipping burgers instead. But RoR, Node.JS et al dumbed things down so much we got brogrammers...
This was the fear with "India" in the 1990s, and how it was going to kill all of our wages.
I make a lot more money now than I did then.
