The world is messed up enough as it is. Ever try to enjoy something and have someone less fortunate get on your case as if what's on their plate is your fault and you could and should be doing more than you actually can?
If you enjoy enjoying things, don't get down on "privileged" people. If they lack empathy or compassion it's because they're victims of the system too.
If they're like that, you're not going to get through to them with your gripes. Let someone in this fucked over world have a moment of peace, even if they suck.
