You're absolutely right, I guess this is the fate of our societies, we never have enough..... Even people who can afford safaris in Africa with 16 L lenses are not happy. But that should not be a reference in any case, I've been on my own traveling enough to see starving people enough, when I start to behave indecently, that very thought puts me back in line. Do not be ashamed of your so called social status, or your income level, there is simply no reason for it. Keep enjoying life as you do, have fun making nice pictures with what you have, if someday you can afford a lens upgrade that brings you something, then go for it. The most important is who you are and what you do, not what you own. I think all this whining about equipment (I confess I am part of it sometimes) just shows how unfulfilled our lives are. When I was 16, I was offered an Olympus OM-10 with a 50mm 1.8, I was never as happy as with that simple rig.
