Well, besides eventual differences in cognitive ability, this probably has a lot more to do with that a lot of teenagers today aren’t responsible for much at all. In smaller communities, you see the event chain much clearer. You probably know who has to fix the ruined thing. Perhaps you even have to help out yourself. To put it simply, you don’t shit where you drink. This of course presupposes that the small community is a community to begin with; connections and relations between people and their environment need work, need to be maintained.

In a modern context or a larger city, you have much less of an immediate connection to the consequences of breaking, say, a streetlight. Someone else has to clean it up, someone else has to fix it, and they probably get paid for doing so anyway. And this is the typical attitude of everyone around you, this is what you learn.

But to turn this around, most of the environment around you in modern society actually has nothing to do with you. In an urban environment, not much is “yours” and you have little direct investment in anything. You’re a guest in your own living space. And with this in mind, why should you care about some streetlight? Or some building you’re not even allowed to enter? Or a street full of billboards for products other people make money from?
