The post-Second World War simple system of social democracy and organized labour has fragmented massively, but just because people aren't organized in workplace trade unions doesn't mean they aren't in associations with other people - work-based, place-based, culture-based, sport-based, faith-based - there's a bit of an old rainbow coalition argument.

Activists can get very preachy about things. It's more about understanding people's own experiences and tapping into them.

You have a huge number of people who spend their time writing papers which show that migrants pay more to the country than they take out in benefits, and they say, "Why don't you approve of migration? Why don't you open up borders?" They're not able to empathize with how people feel about migration.

We should look at how "the enemy" - people that you wouldn't necessarily agree with - have done change and see whether there's bits in there that we could learn from.

In the end, that's a blind alley - we have to get back to being able to think on our feet and react.

In any system, there will be change happening without you.

The magic formula is there is no magic formula.
