Detailed participant history by Presidential advisor and sociologist, of the time America tried to institute a basic income (negative income tax) to replace welfare services. A relatively liberal policy, proposed by Nixon, torpedoed from the left and right. Plenty to relate to today, in terms of public and political opinions of welfare or a basic income, of technocratic policy against politics, and of story telling (and predicting your opponents stories) for complex proposals. But a lot of details.
