There is a substantial difference, to take one example, between a political economy in which organised labour is one of the internal power groups controlling the large firm and a political economy in which that control is reserved for upper management.

Isn't Germany the counter-example? DB's worldwide rapacious financial predation is built on an economy organized around industry in which organized labor has place at the table. To use the image that SKoD used above, the capitalist state has digested such mechanisms quite comfortably.

Mills in the 1950s describes an American power system in which organized labor had been tightly integrated in a subsidiary role. One does not need to be an orthodox marxist to see that the operation of a worldwide system of capitalism is a strong current, not easily diverted.
