Because they are? Outside paying taxes (if you do), your job is probably useless for socially. Or actually shit for the world in the bad cases.
Ultimately, we should all die and let the top 1% have their planet back. Hopefully AI gets us there.
At the very least you're helping funnel money from the average joe and divert it to the uber wealthy, and a handful of lottery ticket winners. Often, you're actively searching for ways to hurt the vast majority of the population.
that's just a tautological argument. They are useless because the are useless?
IMHO, if a job gets pay, it is not useless, because the person paying is implicitly agreeing that the payment is worth the job being done - esp. if it's a private job, rather than a publicly funded job.
It's disingenuous to assume we all have a choice of where to direct our labor. If that were true, nobody would work for bad employers. Humans are exploitative of one another and society is where we formalize it.
