Uber's technology isn't novel and will be replicated. Robot cars will probably make them a commodity. Alienating the frontline is selling the future.
Before Wal-Mart adopted a business model dependent on government subsidy of the workforce, they paid well and gave even part time workers significant discounts on stock purchases. When that stopped, and they took the asshole route, the shopping experience turned into the current state -- a few steps away from DMV.
There's no competitive advantage to paying your drivers well, there's no legal compulsion to pay drivers well, the only reason to pay your drivers well is to be nice.
Your example is bad because the reason all those incentives are offered is because IT workers are in demand and so market forces are forcing employers to offer lots of benefits. Not because they're nice.
But take the IT industry. I just saw a startup offering unlimited Amazon books, unlimited Starbucks coffee, half day Fridays, zero cost health care, and remote work, all in an attempt to attract employees.
I'm not saying the Uber drivers should all go into IT, but there is a shortage of business administrators, educators, and health care workers in this country (and I'm sure lots of other fields).
