Right or wrong?

Today i was in the CTA, from heliopolis returning back to home.
I waited for a long time, about 30 minutes. so of course, the one that arrived was very crowded, and people are standing up. i wanted to return back at home as soon as possible cos i was going to the opera. Anyway, while i was standing up, i heard 2 ladies, also standing up talking together. One said this is wrong, the driver should not allow people more than the seats, and everytime he stops to take more the people shout and say no place. Well the point is, it is against regulation, so the driver should not do that. but also i think it is our fault, the passengers, cos we agree on that, if we say it is wrong than we must be the first people to not do that and refuse it. I don't use the CTA that frequently to say if it occurs a lot or not, rarely i don't find a place.
But what makes me think is that a lot of times, we say it's wrong but just talking, not acting, otherwise, nothing will change.
