Re: ...for rich people.
When I was a Londoner, I was not by any stretch of the imagination "rich" - yet I could afford to take a black cab occasionally.
Of course, it only needed to be occasional, because at least 363 days a year the tube was more than adequate for my needs.
I've never used Uber, and can't imagine myself doing so. On those (very, very rare) occasions when I need someone else to drive me somewhere, I'm still content to take a licensed and labelled taxi. And no, I still don't think I'm rich.
