That's ridiculous. People are less passionate about their jobs today because 1) there are many more unfulfilling, essentially unnecessary jobs and 2) people see more opportunities to switch to new, more interesting work (even if they usually don't take the leap, and even if the opportunity isn't really there). Sometimes people end up in these unfulfilling jobs thinking it's their passion, then have an identity crisis when they realize that they aren't "making a difference" - say, the politics example.
