Sounds like the solution is simple - just split up Germany again, haha.
Well only half-joking, it worked out great for Czechia and Slovakia. Inequality of the regions was one of the main reasons for the split, similarly as you describe it. And funnily enough, Slovakia is also heading in the far-right/populist direction.
