The statistic about children living on "$1.25/day" reminds me of a Facebook meme which I've seen several times.
Its author's intention is clearly to make other USAnians feel guilty about how much they earn, relative to this amount (maybe a popular brand of sweets which they buy for their own kids costs a similar sum).
I do not know what levels of general ignorance pervade the kind of people this meme was aimed at but it is not inconceivable that they're not aware of how cheaply a family can be fed in a country where most of the population is dirt poor.
Pit simply: food does not demand a high price because noone could afford it.
They can't afford much because a day's worth of their labour isn't valued highly
That is because they lack education and are limited to fetching and carrying or cutting sugar cane, to feed some other nation's sweet tooth.
Or they can dig for gold and rare earth metals so that we can have mobile phones and electronic gadgets.
If you give them money, they'll get the same amount to eat, just at a higher price. The food vendors will have a beanfeast until their customers are broke, again.
If we give up our luxury goods, millions in poor countries will have nothing left but picking over garbage sites (and they'll have to fight to get a place doing that).
Industrial revolution began 1850-ish. Just look what happened to world population since that time. Looking at the chart anyone would think that wealth (in the developed world) creates people in all corners of the world.
