That has nothing to do with desire to work. Shitty jobs are shitty jobs, and if employers don't pay enough to justify putting up with the negatives, people are naturally going to do something else. I presume your spouse didn't quit after a year to sit on a couch, she quit and found some other job which was (hopefully) better. A lot of shitty jobs out there rely on the fact that people need to settle to pay the bills. There are people with little experience or going through rough times who simply can't afford to wait for a good opportunity to come along, they need something to hold them over for a few months or maybe years. The employers know that these people have few options and will leave as soon as they do, so they offer low wages and overwork their staff and replace them when they are used up. UBI means people don't have to settle for the first low paying, undesirable job that comes along, they can hold out indefinitely for something better. Yeah, people are still going to need to get their foot in the door somewhere, and some opportunities might be too rare to be considered realistic, so we're not all going to be working our dream jobs, but the worst abusive employment anti-patterns will go extinct.
