‘Overworked, underpaid’ humans train Google’s AI

The title seems kinda misleading, this is from the article (GlobalLogic is the company contracted by Google):

"AI raters at GlobalLogic are paid more than their data-labeling counterparts in Africa and South America, with wages starting at $16 an hour for generalist raters and $21 an hour for super raters, according to workers. Some are simply thankful to have a gig as the US job market sours, but others say that trying to make Google’s AI products better has come at a personal cost."

That argument is as old as any mistreated worker complaining about their situation and as old as any argument against workers rights in general. Anybody not liking their job could just leave right? Simple! No, the world just isn't that simple and it didn't become simpler just because it happens in an AI context that produces a tool you like.

There are lots of jobs out there that suck and people do them anyway. Because the freedom that they supposedly have is not as free as you imagine.

What explains not changing jobs because you find it distressing and claiming that you're being paid below what you're worth? It seems like if that were true, then you'd be motivated to find a job that pays market rate. And if you couldn't, then you could at least find another job that pays less than market rate, like your current job, but isn't so distressing.
