My point is simply that if you are 1 of 50,000 in a meat processing plant, you do not really have any way of competing with your fellow workers. You might try to work harder and faster, but then you end up raising the bar for all, and you now have to maintain the new pace. And once the rest catch up with your pace, the pay for all will be lowered again.
In tech, every job is slightly different, and there is a real opportunity to meaningful differentiate yourself from the rest and compete in a much more dynamic job market.
Also, who are the ones hurting currently? The juniors or the seniors? Seniors are mostly doing fine. Juniors are the ones hurting. And juniors would have an even harder time, if you transitioned to a unionized system, because entry requirements would be raised significantly to account for the fact that you cannot fire people so easily.
