Uber's main success was to take something that already existed (taxi services) but then found a way to work around local labour laws on a technicality.
Because Uber drivers are all self-employed, they're not unionised or protected in any way. Thus, Uber pays its drivers a pittance, and is able to undercut and undermine existing taxi services who are forced by unions and law to pay drivers a living wage.
That's the key to being Uber for X. Ask: can I use the internet and shady business practices to exploit workers to undercut a business that previously workers were protected in?
