What good is a company that is not sustainable enough to pay its employees enough to live?
This is unhelpful, but that's the way things work at the moment, and it's very well understood by aggregate investment capital.
So then you get a second sense: good enough to sustain huge amounts of investment capital from people who correctly perceive that it will destroy other companies that choose to pay their employees enough to live.
Still pretty unhelpful, if you're a human…
$19 is certainly enough to live (~$38k/year). This is way above poverty and one of the highest wages for unskilled labor.
At least it's way more than a postdoc immigrant can count on.
