The big difference is that in much of Western Europe, the combination of social security, healthcare, pensions, social housing, eduction costs, public transport etcetera means you don't rapidly fall out of the middle class even if you lose your job.
As a result, there's much less talk about the "decline of the middle class" in Europe. There has been no dramatic change.

All those things depend heavily on a solid government budget, with solid income from taxing a strong economy. As we're now seeing with Greece, they're not sustainable if the government "coffers" are emptying up or if the economy is weakening.
