It would probably look a bit more like Germany, FWIW. Bit late now of course. And no, the old structures are toast in favour of individualism, but that wasn't the question - it was how to appeal to people in (say) northern satellite towns. So invest in deprived areas a la EU regional development, flawed as it may have been, whilst reconfiguring the national economy (subsidies, taxes, legislation, infrastructure, public spending) to encourage something other than banking.
It's far from impossible - for example Nissan didn't pitch up to Sunderland of its own accord, and JLR didn't make a success of its Midlands operations without a lot of supporting preconditions. Not nearly enough, but a pattern. So form and properly articulate such policy, believably so, and then we'll see whether it wins votes in such places. Sounds like a bit too much like hard work though.
