This! We are a single income family, and we have to be very frugal with our budget. But, even so, I consider myself lucky to have the education and opportunities I do. Many people, even in the US, don't even get that, possibly because they're having to take care of a family at a young age, have trouble getting a decent job because of a their lack of education, are physically or mentally challenged, simply don't know how to break out of their situation, don't speak the primary language of the area, etc. Even getting to go backpacking at all is a luxury.
