"There are two kinds of politicians, insiders and outsiders. The outsiders prioritize their freedom to speak their version of the truth. The price for their freedom is that they are ignored by the insiders, who make the important decisions. The insiders, for their part, follow a sacrosanct rule: never turn against other insiders and never talk to outsiders about what insiders say or do. Their reward? Access to inside information and a chance, though no guarantee, of influencing powerful people and outcomes." -- Larry Summers, according to Yanis Varoufakis in "Adults in the Room"
