Usually Keynsian economics is understood as economic thought that is based on aggregate demand, this is for example the view Wikipedia takes. [1] From there it is straightforward to argue that higher wages lead to higher employment, a view that makes Keynsian economics popular on the left. The view, that too high wages cause unemployment, is a staple of supply side economics, the view that the economic process is driven by the supply side. Krugman argues a lot about sticky wages recently, but not because this is a central tenet of Keneysian economics. Krugmann argues about sticky wages because it is a good argument against the troika's handling of the Greek crisis, since the internal adjustment in the Euro area would either mean inflation in Germany or deflation in Greece.
