I've been wary of lifestyle inflation for a while, so that's why I avoid developing a taste for fancy coffee, and I will never try the
$35 pick.
Taste inflation, which is a cause of lifestyle inflation, has got me, though. We just picked up the next two Percy Jackson books and a Smartest in the Universe book. That's about a week and a half of reading that is about as satisfying to him as someone watching The Wire for the first time. There is basically always a really engrossing book for him around the corner.
I think I've finished about a quarter of the fiction books I've checked out. I think the last one was You Dreamed of Empires. It was good, but I wasn't like oh man I gotta spend all my spare time on this.
I have no real conclusion about this. I wouldn't want to be one of the millions of adults that's into the Marvel movies, but at the same time, I do want to feel like there's a pool of engrossing entertainment available to me that continually refreshes.
