McDonald's would have automated those jobs away regardless of labor supply, and whatever alternatives there might be are going to be automated as well. Entry-level work is categorically being done away with, and yet the expectation of social and business skills being provided by entry-level work is not.

I suppose that this is correct, but mostly because of the cost-benefit analysis. If labor is more expensive than automation, then the company will turn to automation. Automation is getting less expensive and labor is getting more expensive, so here we are.
