Yes, people prefer to make a little bit of money instead of not having money. This is surprising?
And when someone earns a little bit of money, they might wish that they made more money. Again--not news.
I think before getting critical about why Uber drivers are so dumb, it's worth thinking about why you don't drive for Uber. The answer probably starts with "because I don't feel like I have to." It does for me.
If someone has a great highly-paying full time job and still drives for Uber, then sure, question that person's judgment. Most Uber drivers are not in that situation though.
