I hope you're trying to be on the workers side but either way this is a terrible thing to say. The way you look down upon people trying their very best to make a living is not helping them at all.
It's dehumanizing to work and get paid little or nothing at all. You seem to be reading much more in the comment you're replying to than was actually said.
Depends on the sort of tasks you're doing. Someone above mentioned receiving ~$0.27/min of translations. This is a relatively high figure in comparison to a lot of tasks, but if the task you're doing isn't entirely mind numbing then being a Turker isn't as bad as it sounds. $0.27/minute is something like ~$16/hr - if you're working at a gas station with a computer handy, you'd be able to more than double your wage. Are the tasks undervalued? Not sure it's fair for us to say. The HITs keep coming in and they continue to be completed, so something is working.
Depends what sort of gas station you're at, I guess. My sister worked at a gass station one summer. She was mostly alone on the job, kept an eye on everyone who filled gas, made fast food, made sure the shelves were well stocked with products and cleaned. Not much room for going to the toilet much less sitting at the computer, but then her wage was something like 30 USD/h.
