There has been to my mind a very silly debate about whether Trump supporters are driven by racism, xenophobia, and misogyny or whether they are driven by economic factors.

I consider this debate silly since both are obviously important in my view. Racism, xenophobia, and misogyny are deeply rooted in society and few of us can claim to be completely devoid of these sentiments. The question is how these hatreds can come to be the defining feature of political life for large numbers of people and here I think the economic policies of the last four decades have played a crucial role.

I would argue that we have pursued policies that have been deliberately designed to shift income upward over this period.
