Yeah, but you had at least a decent camera & computer. Not everyone has parents, friends or someone who can support them either by paying them or lend them those relative expensive things.
Your are probably baiting, and our answers are pointless, but if it's isn't the case then you are probably just narrow minded.
Some high educated people have also to go for kind of jobs as their studies don't bring them decent jobs as there are no jobs left in their sector (humanities studies have this problem).
Also, msot of those people are involded in retail only a small part of their life, as a start as they need money for something else (travelling, start their own bussiness etc)
