You kid, and it would be kinda horrible in certain ways, but I genuinely think it would increase ridership significantly.

Let's face it, classism right now manifests as:

* poor folk use terrible public transit

* med income folk drive cars

* high income/wealth folk get driven around by robots or staff

At least with the classist train you cut down on emissions and public funds spent fixing roads. And I'd argue it's a bit less unequal than the status quo in 95% of the US.
