@rbreich Malcolm Gladwell talks about strong link vs. weak link systems. In a strong link system, the strongest individual is most important to success. In a weak link system, the weakest links are the most important. Our economy is driven by demand. The stronger consumer demand is, the better the economy. And demand is a weak link phenomenon.

Supply side economics is a strong link strategy. It it argues that it's capital which drives economies. But capital is rarely in short supply.
