Sounds like you have a specific axe to grind Snoopy.
I have lived in the north and down south, and am a northerner married to a southerner and my considered opinion is that the standard of living up here is better, but employment opportunities far less. Matters have improved a lot since the Tory "social experiment" of the 1980s, but if you're a career person you're still better off down south.
As to my opinion of southerners, I don't have anything against them per-se, just the one or two twats who look down their sneck at the north.
Was the "grim up north" reference no originally a reference to industrial, not economic conditions?
