A well paid slave, is still a slave.
It is simply risible to pretend that the tech-industry has not created a new generation of piece-workers. Or that conditions cannot be bad (even unacceptable) in a well-paid and otherwise privileged job.
Perhaps you simply lack insight to realise that by writing this comment you have become the thing my comment was mocking? :)
"You Gladiators, look at the purse awarded to you! And you call yourself a common slave! It is an insult to the slaves who toil in the mines!"
