My local park back home doesn't have anything like FastPass so when I heard about it, I was excited because I only had a few hours to spend and promptly got it as soon as I got to the park. As I walking to the first ride that I pre-reserved, I came across a family, all wearing the same t-shirt; the kind of shirt you have pre-made for a family event like an outing or a reunion. I thought that was neat and went on my way.
Fast forward to an hour or so later, and I see the same family at one of the coasters, standing in line while I walk right ahead and past them to the front. I start to think -- geez, is this sending the right message to this family, that those with more can just zoom ahead?
(As a very imperfect solution, I ended up running into them yet another time, right as I was leaving, and I gave them my FastPass.)
Life is fraught with a lot of those ambiguities. Or at least I think so. I order DoorDash, even though I know I'm getting convenience at the cost of a exploitative system for the vulnerable and underemployed.
There isn't a "correct" answer, just as there's no "correct" answer to the seat problem. Everything is relative. I do tend to think though that with a little empathy for everyone else, you'll do pretty well.
