Day-old bread? Sadly, in America a lot of day-old bread just becomes nasty. Italian day-old bread, not having any preservatives in it, just becomes harder and it doesn't taste old. What I would warn people about is getting bread that's loaded with other things in it, because it starts to taste old.
I see bad stuff on the street all the time that I don't do anything about. I do bad stuff myself all the time. The goal is not to somehow be perfect - that's silly, that's naive. The goal is to just recognize there are choices in front of us, and to try to make better ones.
