There's also going to be a shrinkage in the workforce caused by demographics (not enough kids to replace existing workers).
At the same time education costs have been artificially skyrocketed.
Personally the only scenario I see mass unemployment happening is under a "Russia-in-the-90s" style collapse caused by an industrial rugpull (supply chains being cut off way before we are capable of domestically substituting them) and/or the continuation of policies designed to make wealth inequality even worse.
