Yes they know about that just like they know about the plague and the possibility of an asteroid stroke destroying life on planet earth. But is inflation a big part of their day to day worries? Probably not. Political extremism maybe, but they're probably wrapped up in that as well. We've created a society where if you aren't openly fighting the bigots you are seen as allowing them to exist. So teens are very politically active and I wouldn't be surprised if it stresses them like it stresses adults. But unless they're experiencing poverty I don't think kids are getting depressed because they're worried about wealth inequality. Unless the teen in question is Karl Marx
Around 11 million children in the US live in poverty. A great number more children are poor to very poor (just over poverty might not be poverty, but it makes your life pretty bad). It probably isn't so bad in a country with a robust safety net (still poor, but not getting the full effects of poverty)
I don't know about wealth inequality being the specific worry, but knowing things are getting more expensive definitely has an effect on children. Suddenly, the parent is stressed and the uncertainty gets passed on. Though, I honestly am wondering if I've missed something because while I see things about money and inflation mentioned, I haven't actually seen folks mention wealth inequality.
