2015 he moved to the mayor's Center for Economic Opportunity, as a special policy advisor. Along with Elizabeth Taylor, the literary editor of the Chicago Tribune and Cohen's co-author of American Pharaoh: Mayor Richard J. Daley, His Battle for Chicago and the Nation, Cohen is also co-editor of The National Book Review. In 2017, Cohen was a Pulitzer Prize juror in the category of criticism and in 2018 he was a juror in the category of Feature Writing. Cohen is the author of five books. The most recent, Supreme Inequality: The Supreme Court's Fifty-Year Battle for a More Unjust America, argues that the United States Supreme Court turned away from protecting the poor and weak and from advancing a more just and equal society across broad and diverse areas of law (education, poverty, campaign finance, democracy, workers' rights, corporations, and criminal justice), reversing the course the law had been on under the jurisprudence of the Warren Court.

Nixon went on to appoint four conservative justices (new Chief Justice Warren Burger, future Chief Justice William Rehnquist, then-conservative Associate Justice Harry Blackmun, and Associate Justice Lewis Powell). Calling the book "impressive and necessary", The New York Times praises Cohen's "sweeping review" as showing that "the Court has repeatedly engaged in judicial activism against the poor", aggressively exacerbating income inequality in the United States. "Cohen sums up the result of fifty years of jurisprudence in the areas he explores, writing that 'the post-1969 Court has been working unrelentingly to protect the wealthy and powerful, and to make [the United States] more hierarchical and exclusionary - and it has been succeeding. When it comes to the law, and its many consequences for society, we are all living in Nixon's America now. Asked to explain how he reconciles the post-Warren Court's progressive-leaning decisions on gay rights (marriage equality), curbing executive powers during wartime and (some) reproductive freedom decisions with his narrative of a reactionary court, Cohen responded, "Well, you might just say that in a capitalist system like ours, wealth and money and the current income and wealth distribution are really where the rubber hits the road. Look at how corporations actually
