I use taxis far more often than I use Uber and I vehemently disagree. What evidence do you offer for such a statement? Most taxi drivers in France are hardworking, independent businessmen who own or lease their own cabs and are only rather loosely affiliated with a dispatch service, predominately Taxi G7.

Specifically, what market conditions have these people created? Only taxis give fixed rate fares from the airports into Paris, and they do it with no surge pricing.
