“In the United States now, the city with the highest per capita income in America is Washington, DC. They passed Silicon Valley last year. Seven of the ten wealthiest counties in America are counties that border Washington, DC, so government has become big business. There’s a lot of money to be made. And not only is that leading a lot of young and talented people into influence-peddling in industries where I’d rather have them doing something more productive, it’s also changing the entire incentive structure. We know for example that hedge funds that invest in lobbyists and make a lot of campaign contributions actually consistently outperform those hedge funds that don’t.”
