This video discusses the challenges facing the Democratic party, particularly the exodus of residents from traditionally liberal states like California, New York, and Illinois. Ezra Klein argues that the high cost of living in these states is driving this trend, leading to a potential loss of political power for Democrats. He uses the example of California's high-speed rail project to illustrate how liberal policies, while well-intentioned, can lead to inefficient and costly government failures. The core argument is that Democrats need to shift from simply defending government to making government work effectively.
