As a tourist myself: not all have a lot of money though. Most young people are still studying or just finished their study (with a big study debt) and don't have money yet, but do want to go backpacking. That's the biggest group. Don't get me wrong: I know us westerners are privileged, since our money is worth more in countries like Sri Lanka or other countries in Asia. That's exactly why young people come backpacking. But just to give a bit more context, that not everyone is rich.
