*Cool paper alert!* Similar to my paper, where data increases inequality via returns to wealth,

True, real power lies in the nexus between K Street and Wall Street and it is not helping the poor!
Today six financial institutions have assets equivalent to over half of our GDP.
They determine whether workers can earn a decent wage or have health care or not.
There will be no real change in this country unless we have the courage to take on Wall Street.

The age at which scientists or innovators achieve their moment of genius has been increasing. Half of all pioneering experimental contributions in science happen after age 40. The increase may be because there is so much more knowledge to master nowadays.
