This is a good example on how the exploitation works. By gaming the system and picking off the best orders you’re making good money but these type of comments are Survivorship bias . Doordash model makes money off of all the orders in aggregate and needs a steady supply of churners to pick up all the rest of the orders and deliver. MTurk has the same model. When it started I did it for six months and made +$20 hour by figuring out the system and using software to snag the best jobs but amazon makes money from all the penny machine learning jobs and not the occasional $15 psych study. By gaming it I helped guarantee new people on the bottom would churn $2 hour for a month and wash out. The insidious nature of it is that they use us to exploit ourselves.
