Because there is an entire generation of driver now weaned on Uber. They're all over London: guys who got a foot onto the driving ladder and know no other way. They take what they're given.

The disaffected professionals are probably the ones who bitch and gripe about money compared to the old days. Uber is now trying to swallow up huge amounts of market share by creating mammoth demand which will presumably lead to more drivers (who haven't been weaned on better-paying services).
