That's true. It's economics.
Specifically, the only way you can reliably manage it in current Western culture is via economies of scale. A factory-kitchen feeding 5000 kids and distributing meals to schools will probably do so for under $1/day by exploiting those economies of scale. However, you don't need to be Jamie Oliver to realize that the food in question is never going to be exactly great. Or nutritious. Or sustaining.
Could i - personally - feed myself for less than £1/day? For a week? Sure. A few rabbit snares, fishing with worms (it's not cheating when you're starving), maybe 5p for a handful of raisins to take a couple of pheasants with.... none of these are an option if you live somewhere urban (unless you enjoy the taste of fox or cat or you decide bin-diving outside Tesco is allowed). Almost none of these are an option for kids.
And don't pretend you do it, either. Not without a freezer and fridge at least. Seriously man, I'm with Tim on this one. "Raising awareness" is almost always bullshit and often actively counter-productive but this challenge - raise a few quid and actually start to get an idea of how the other half lives - cannot be a bad thing. Why do you have to scorn even this? Isn't sneering at every single new piece of technology that arrives enough for you? Who pissed in your cornflakes? And did you still count them toward your $1.25/day?
