Despite the political problem being created by wage stagnation, employers and employer groups -- against their own interests -- appear dedicated to trying to perpetuate it. 

Wage stagnation, and associated perceptions of economic unfairness, are at the heart of the bitter resentment toward liberal economic policies across the west. Governments and central banks continue to insist that tighter labour markets will lead to higher wages, but either that simply isn't happening (we quizzed some experts on why that is last year) or, in the United States, minimum wages have started rising but the "hollowing out" of middle incomes, leading to dramatically worse inequality, has continued apace. The political dislocation and economic policy retreats that have characterised the last couple of years will not end until wages growth returns.
