What sort of transportation? Are you talking about based on income level? Age? Could you clarify?
Obviously my experience is anecdotal, so I'd be interested to see if similar patterns are true elsewhere. But when there are so few companies competing with each other it seems a lot more likely that there's some sort of regulatory burden or capture in play rather than simple greed. Capitalism might explain why a service with few competitors is expensive but it doesn't explain why there are so few competitors to begin with.
This is literally the endpoint of Capitalism without regulation to prevent monopolies and a floor of public goods. You absolutely should blame it and those who fail to either check or dismantle its power.
Throughout American history, corporations have explicitly undermined and destroyed public transportation so they can profit from it. That’s why things are so bad. First they did it to sell individual cars and now to sell taxi services. Uber’s express ambition is to become the transportation monopoly you decry.
No, they've been doing this since at least railroads, the OG monopolies
We're quickly derailing from my initial point though, that however things got here I think Ubera new service has the potential to relieve a lot of people in a market which I believe is inadequately served at the moment.
