Personally I don’t think Uber drivers are as stupid as you think they are. They legitimately want to be able to drive flexibly. Also they keep about 75% of receipts for their driving (average gross margin for Uber is under 25%).
That's good because that way they can pay for their car insurance, health insurance, pension, gas, car maintenance, self employment taxes, frequent car cleaning, &c.
I'm not saying the drivers are stupid, I'm saying Uber &co are very smart.
Not sure how else to read your previous statement.
