Just finished @DavidLammy's excellent book, Tribes. The key takeaway for me: the left cannot only focus on economics as the solution to our country's divisions (though v important), it must pay as much attention to social connection & cultural belonging. Otherwise...
the left leaves a huge cultural gap for the far right and the likes of Farage to fill. We must promote a civic (not ethnic) nationalism based on shared rights & duties, a new UK constitution, a strengthened national civic service, permanent citizens' assembly and more.
And together with this we need to support locally focused initiatives which connect people across ethnic, religious, generational and income divides, building trust, reducing prejudice and helping overcome the epidemic of loneliness.
This is not to reduce the significance of economic policy at all, but compliments it. Policies to strengthen social connection & belonging and those reducing economic divides will both help re-unite the country and tackle tribalism. No single policy 'lens' has a monopoly on truth
