This is heavily dependent on where we are talking about. I live in a fairly rich place and here, taxis were fine, too. When Uber came, they mostly just eroded salaries and protections for taxi drivers, while lowering the quality of service for customers (though also, for a short while, the price). The best I can say about it is that it accelerated the digital transformation of the industry a bit. On the other hand, I heard from several people from other places in the world that the arrival of Uber meant that they could finally get a safe and reliable ride.
