Wealth is absolute. Since the Baby Boomers' DoB, many people have got wealthier, very few have got poorer.
Now, here this: millions of people are starving to death every year. Starving from lack off food, water, ideas and hope. And Obama isn't gonna change it one bit.
And it's true that millions of people are starving every year, dying of preventable diseases, etc. But those things correlate strongly with extreme poverty, and the number of people in extreme poverty has dropped dramatically over the last 25 years and continues to drop.
