Slaves isn&#x27;t the right word because they enter into that contract by will, though perhaps sometimes by necessity.<p>I&#x27;d say that the results for them are poor on the a large scale, but not necessarily noticeable on an individual scale because one of the biggest factors is uncompensated risk. If you don&#x27;t lose your car while driving for Uber, no problem-- but a big problem if you do, which definitely happens sometimes.
