I agree with the permit restrictions in San Francisco. Without it, you would have monopolies dominated by big business and the rich, which hurts minorities from having their own taxi services. Uber is a clear example of the rich trying to take over business from minorities and people who need money most.
Really. Please tell us which taxi firms are minority owned and operated then, since you seem to have joined HN specifically to educate us about this issue. I'm curious about this, because there seem to be far fewer Asian or Latino cab drivers than one would expect from looking at the city's demographics.
Perhaps you can also explain how it benefits minority folk who have arrived in SF in the last ~30 years that virtually no new medallions were issued from 1978-2010 despite a ~15% increase in the city's population during that time.
