This is just the latest incarnation of a much older strategy. Jonah Goldberg’s book Liberal Fascism described how the Roosevelt administration sought similar consolidations of American agriculture and business during the New Deal. As Goldberg noted:
[If] you want to use business to implement your social agenda, then you should want businesses themselves to be as big as possible. What’s easier, strapping five thousand cats to a wagon or a couple of giant oxen?Similarly, it will be much easier for the government to control 100 large "Accountable Care Organizations" than 100,000 individual hospitals and private practices.
