I think you're absolutely right about finance being geographically imbalanced. Finance can't operate well at scale, it would seem. Finance can't process "the long tail." And when it attempts to, deployments of capital get riskier, more speculative, frothy, etc. It's a missed opportunity that hurts potential customers as well.

I have to disagree with your take on Keynesian macroeconomics, however. Republican protests against raising the debt limit are for show & they always capitulate. Plus, concerns about inflation from Republicans are not as pressing a problem now that they control the purse strings. :)

I think you could have removed anything about Keynes and had a perfect comment. Your note about Sand Hill Road is spot-on.
