The more necessary component of the shift has been to extend childhood a few years further into the third decade.
This has the effect of keeping people out of the workforce, thereby keeping the unemployment rate low in the face of fewer actual jobs due to increases in efficiency from automation.
I don't think I've seen a single policymaker say that this is the reason for subsidizing student loans. Let alone explain why this is the best way to go about solving this problem. At least Depression-era work programs had the advantage of being actual work producing actual useful results.
Look at SGM's situation in the context of your thesis. In that context, we're not loaning her money so she can delay entering the workforce until she's more employable. We're loaning her money to stay out of the workforce because there's just not enough work to employ her.
Not only that, but she uses the loan to get a degree that is also not particularly employable.
Not only
that, but the idea of actually doing useful work to repay the loan is now offensive and punitive to her.
Not only
that, but the useful work that's been suggested has always been around. If she were going to do it, she could have done it just as well six years ago. There was no need to loan her money to stay out of the workforce after all.
Anyway, if we need to pay some people to stay out of the workforce because automation needs less jobs, I'd like to see a top-down review of the entire process. I'd like us, as a society, to say EXPLICITLY that this is what this money is for, and this is who it's being spent on. I'd also like to get a place in line for some of these "please quit your job so other people can have it" payments.
In fact, if we're going to pay people to drop out of the workforce (temporarily or permanently), we should probably do it in the form of early retirement incentives to people who have already worked for some decades to contribute to society. That way, young people can enter the workforce in the usual way, and make their own contributions to society, instead of getting paid by the contributors to
not contribute. In a sense, SGM should be paying me to not work, not me her.
