Last week we talked about British Labour Party leader Jeremy Corbyn’s cunning plan to allow Brexit to go forward in the hope that he and his party might take power in 2020 or 2025 and use restored national powers to move Britain sharply to the left. It’s politically tempting for some on the left to return to the nation state–many working class people in many countries want to see tighter controls on immigration and a renewed emphasis on national sovereignty, and if the left triangulates on these issues it might make itself more competitive with these voters in the short term. Some on the left now believe that international institutions are irredeemably neoliberal, that there’s no prospect of regional or global cooperation to restore the tougher tax, wage, and regulatory policies of the post-war era. Right nationalists are doing well, and the fight between nationalists and internationalists seems to be one the internationalists are likely to lose. So why chain ourselves to creaking neoliberal institutions like the European Union? Surely this is an albatross the left can do without, right? This all may sound plausible, but it’s a big mistake.
