> A "shit job" is by definition one that creates little value because value is defined as what is lost when someone exits the picture.

There are two people involved in the transaction: the worker and the employer. The employer will value the work at a value greater than the wage, otherwise they would be more profitable just by firing the worker. Similarly the worker will value the wage more than the job, because otherwise they would quit.

When most people talk about the "value" of a job, they tend to not use either local definition, but from a more global definition of "how bad off would society be if nobody did this job" and that more closely aligns with the employer's value than the worker's (e.g. for services jobs the employer makes money on the spread between what customers will pay and what workers will work for, so clearly customers value the job at some margin above the wage, and we can use customers as a proxy for "society")

Without UBI, the wage is what lets the worker not end up homeless and starving (or begging), so someone with no better job prospects will value the wage very highly. Once you add UBI into the mixture though, maybe it's "move into a larger apartment" or "eat out somewhere nice once in a while" and suddenly they value the wage much less.
