I don't want anyone working a job to live a subsistence lifestyle, but taxis have also always been a nightmare for me (in the US and every country I've ever been in) and I never want to go back. Uber and Lyft are vastly superior and less stressful experiences for the customer in every way. I'd like them to be good experiences for the drivers, too, but the answer isn't to scrap the whole thing and go back to taxis.
In some countries, the meter is just for show and every ride is a negotiated fare. Also, sometimes it's hard to distinguish taxi from pirate. Heck, in some places, even the licensed drivers are notorious for robbing tourists. Yikes.
