Lyft and Uber Drivers

There is a CA proposition about reclassifying Uber and Lyft drivers as full time employees. Why? Is California trying to dissolve these companies? Normally, I'm a pro-labor guy, but I'm sorry - being a Lyft or Uber driver is not a profession we really need to protect, is it? Isn't this just a part time job for some folks looking to make money between things? Isn't that what it ought to be?

And note: most of the Lyfts and Ubers I get rides from are in better cars than my own. What does that suggest?
