What?
In what world do Vacations and Backpacking and Camping require little to no money? Those are expensive activities in both time and raw cash. When you don't have a lot of money, food is also not something you get to be picky about because you don't have a choice -- You can eat what's on the table or you can literally starve. That is the real circumstance for people living below the poverty line in this country of which there are plenty (http://www.nccp.org/topics/childpoverty.html).
What bugs me is there are a non trivial number of people, yourself included, who are entirely blind to the circumstances of the poor and struggling. These are the people who insist that if you 'just work hard' you can make it, or that education is some kind of great equalizer. These are the people who also generally have a lot of influence in politics, both locally and otherwise, and proceed to campaign against what little social safety net we have because they couldn't be bothered to give up a fraction of their disposable income so millions of people could have food to eat and running water.
