Heh. I'm very far from anti-work - I had a fellow busker in my very early days nickname me "Cappy" (ie capitalist) because I was such a dedicated hard worker out at all possible hours (though this lifestyle did have a certain flexibility that I enjoyed immensely). I've since mainly been a small business owner and worked incredibly hard at times, up to 80 hour weeks - though not always.
I would agree with your stance, truly - if we could time travel back about 30 years. As it stands now, automation doesn't give a crap about your unemployment, and spending years developing a JG program would maybe deliver something juuuust in time for it become obsolete. The psychological effects would be better mitigated by simply getting ppl used to the idea that they don't need to work to deserve to live sooner rather than later. I know you have been saying all along that you want to deliver UBI alongside JG, again, which is very noble, but I think will have been a waste of resources by the time any such program could actually be put in place. The market is already moving very fast, and is only going to speed up.
How do I know this? What is my evidence? 2 weeks ago had client tell me he had to leave a formerly secure job in a mine they've worked in for years, because the mine is about to go 100 percent automated within 12 months (this in WA) ... and the new place they've moved to? ... you can guarantee it will do the same thing in the next few years, or become uncompetitive. Client working in law... they are ok themselves (for now) but tell me there are a TINY fraction of the jobs for juniors and paralegals even NOW let alone in a few years time... because the grunt work is already being outsourced to AIs. Mainly in Ireland, I believe, so AU doesn't even get tax $...
Same for accountants
Same for HR departments
Same for supermarkets
these are all examples from real conversations with real people that really aren't needed in their jobs either now or WITHIN A FEW years from now, guaranteed. Probably a few I haven't spoken to unemployed or underemployed who I won't see in future that I don't even know about... and I'm scared too, because if current clients become unemployed... they aren't going to be able to afford my services either, and my income will also be reduced, and the economy shrinks further.
This is not going to be saved by a JG which will attempt to fit their existing skills into a hole that doesn't exist because it's been filled by automation. Better plan to offer free education, reskill and allow ppl to fill the demand the market creates with new real jobs in new industries that we can't imagine yet. Smaller government, better outcomes overall. No one starves and all the negative impacts you exhaustively list start going down naturally because if a JG exists, there is going to be stigma that if you don't take it up, you aren't really trying /don't really deserve to exist.
