Are you guys loaded, that you can afford not to get paid?

No. We have fairly normal jobs. However, some people enjoy collecting rubber stamps. We enjoy travelling. Far away. Also, since we want to go to Japan or Australia anyway, we thought it would be a good idea to try and make it cheaper by getting as many people as possible to come along and get discounts on flights and apartments, instead of just going with 3-4 people and paying full price.
