The problem with your narrative is that: (1) Traditional taxi companies don't usually have employees. They mostly have independent contractors - just like Uber (2) In many areas, taxi drivers actually pay the taxi company for the right to use the taxi. They do so because the taxi company owns or rents a government license required to operate a taxi. If the exercise is to compare being a taxi driver for Uber or a taxi driver for a traditional taxi company, in many areas, there is no case to be made that Uber offers worse working conditions.
