Of course it was shared. I see the conflict that you are trying to present but that's a problem for employers to solve. Livable wages and treatment may keep more people working retail instead of just opting to stay on UBI. Give people are reason to stick it out in a dead end job over UBI.
Also, retail jobs are drying up as is so UBI is a necessity either way.
The conflict that exists is that there's a market interest in bottom-tier merchandise. That is to say, the disposable crap that Macy's, Old Navy, Gap, Amazon, WalMart, Target, and a thousand other bargain-priced retails stores sell. It would be pleasant if there wasn't a market interest in it, but it's clear that consumers want $5 shirts from Target and $20 jeans from Macys or Old Navy.
You (and others -- me included, my dead end
retail-like job was in food services/hospitality) had that dead-end retail job that you hated
because you (and others -- me included here) are the consumers who also want a $5 t-shirt at Target or Old Navy. Now, I'm not saying basic income is impossible, it isn't, but eliminating the dead end job that you had because of your consumer tendencies doesn't eliminate just
your job it eliminates the thing that tens of millions of people want: cheap throwaway shit. Now, maybe cheap throwaway shit
should be eliminated, but we've just expanded the scope of basic income to not just getting you out of the job that you hated, but taking away the thing that you probably don't hate (or at least, fewer people hate), cheap shit from Target.
And then, of course, we have to question the theory that you posed. If Basic income is allowing you to pursue the office job that pays a little more money instead of working in retail that you hated, wouldn't your other coworkers in retail who also hate their jobs,
also be going for those office jobs? If there's more employer demand for those office jobs, wouldn't they then become harder to get,
or wouldn't the quality of life that the office job has then
come down to the level of retail? So, would you go from hating the dead end retail job that pays shit (an employer problem as you put it), to being the dead end office job that pays shit?
In this case basic income isn't liberating you from the retail job that you hate. It's liberating you from the retail shit that you
probably like, and replacing it with the office job that you'd probably also hate.
I'm not against basic income either, but I am against the idea that basic income would be easily implemented and would just exorcise us from the things that we hate so we could focus on the things that we like. Given human history and its tendency towards a supply and demand economic framework, I think the reach of basic income would be a lot larger than simply lifting you up from your retail hell (which, btw, are you still working in retail today?)
