That's stretching the definition of "rich" beyond any possible meaning. But yes, if you want to talk about the middle-class, which is what you seem to actually be referring to, let's. In most cities, they've already dropped out of buses. They take their own cars. A more expensive bus service like Uber's probably isn't going to taking much ridership away from public buses, but rather give middle-class people more options, so maybe they don't need a second car. And again, bus systems are remarkably scalable. Unlike things like subways and light rail. Routes and capacity are extremely flexible. Just because there are more transportation options, doesn't mean there's going to be a demise of city buses.
