Unionized Chinese? Communist China can teach America thing or two about capitalism...
German labor unions in the automotive sector are arguably the world's most powerful. But the integration of politicians, white collar management and union labor in Germany is uncommon; only Japan or Korea are as integrated as far as I know. Corporatism is a modern model of fascism without authoritarianism.
I'd be ready to bet that of its 3 similar factories (China, Germany, Austin, TX) the Chinese will always be more productive, the German will always suffer the most work stoppages, and Austin will always be the least productive.
