"If we’re observing a situation in which capital has become plentiful relative to entrepreneurial ideas, shifting the balance of power between investors and founders, then the natural question to ask is whether we have more capital or fewer ideas. It seems to be fashionable in some quarters to say we have a shortage of ideas, but I think this is hard to quantify. What’s clear is that we have a surge in capital. This has been a bad decade for developed countries, but the world as a whole has gotten dramatically richer over the past 15 years (think China, India, commodity exporters, etc.), and the United States has attracted big inflows of the money that’s resulted."
