The city of Sheffield, a one industry city of steel, was virtually
killed by allowing imports of cheaper steel from abroad.

Sheffield actually produces /more/ steel today that it has done in
the last half century. The difference is that is uses far far fewer
/people/ than in the past. The devastation of steel employment in
Sheffield initially sprang from local companies seeing each other
as their competitors instead of seeing Japan and Korea as their
joint competitor, and a reluctance to retool with equipment that
required fewer workers per unit of product. It took decades of
collapse, bankruptcy and mergers to produce the industry that
remains today, producing more but employing less.
