If you've put off reading Thomas Piketty's Capital in the 21st Century, you can dip your toes in the water with Stephen Colbert's quick primer on income inequality, generational stagnation, r is greater than g, and other economic concepts all the cool kids are talking about this summer.
"When you have no growth in wage and it's stagnant, it's difficult to start accumulating wealth out of nothing. Whereas, if you start with some large initial wealth, it makes it easier to enter the game," Piketty argues.
Colbert pithily sums it up as "Capitalism benefits capitalists."
If you learn nothing else from this video, at least you'll come away being able to pronounce "Piketty" in both 'Murcan and French.
