Working as a "turker" on Mechanical Turk, or as a Tasker on Taskrabbit, or as a Lyft/Uber driver, all have one thing in common: the switching cost to/from that particular job is almost zero.

In my view, this is why you can get paid less than what you deserve, but that option is still attractive to you.

In other words, if you have 34 minutes between things, one of the few paying things you can do is MTurk, even if it doesn't pay well.
