It's a useless sentiment, to be honest, employed by the self-righteous to make themselves feel better than whomever they're trying to belittle. It's hypocritical, too - do you REALLY think that everyone who's ever said this actually gives a damn about starving Ethiopians? No. They care about making themselves look better than you, which - of course - has the opposite effect.
Yes, people die all over the world. Yes, it's bad. But there's fuck all I can do about it and there's fuck all they will, so let's try to be mature and focus on what's actually going on.
I'd love to help people overseas in a tangible, practical way[footnote]I mean actually flying over there and distributing aid/supplies, rather than shipping off a few quid via a charity service. Not that they're somehow worse, just it doesn't feel as useful[/footnote] but that's not exactly convenient or, um, possible at this point in my life, so I'm afraid it'll have to wait until I have money to spare for plane tickets and things to give out to those who need it more.
