No, Dutch society is in principle very bourgeois, left wing parties have only been able to form a majority government by ruling together with the centrist christian parties, either protestant or roman-catholic.

Furthermore the socialist party portray themselves as the true left wing party, the greens are confusing liberalism in society with liberalism in economic policy and Labour is somewhere in between. Also the greenleft party usually derides the socialists and Labour as old-fashioned and like now does not want to co"operate with them, because they themselves are the only true progressive (tm) party.

Or to exaggerate a little, the greens are the student city dwellers, labour the old poor people on the country side, although only in certain parts of the country admittedly, and the socialists the new working poor.

And yes, german politics is kinda like dutch politics.
