Yes. This is true as well. I'd never say our current system is adequate, just that people whining about how crowded a platform is or how they couldn't get on the first train because it was full have obviously never been to a "World Class City," where I've had that happen to me multiple times. NYC having a huge rapid transit system doesn't mean people can get on a train in midtown Manhattan at rush hour and expect a seat. The trains fill up heading south, just like they do here. But here everyone gets all, "It's not fair that I got on at Eglinton and couldn't get a seat!" It is fair. Because the system serves more than just you and you're in the middle of a long, crowded line.
And when the system gets huger, and the Crosstown opens, it'll probably get worse. It's a Catch 22, at best.
