The value of a trade union in a coal mine

Historian Wu Si

Historian Wu Si looks at the backgrounds of the Shanxi brick kiln scandal in Southern Weekend (here in a translation of Danwei). At the tail of the story he illustrates how the arrival of a trade union in the Zaozhuang coal mines made a difference:

Wu: Last year I wrote an article that calculated the wage difference between Zaozhuang coal mines with and without a labor union. Before the labor union came, the workers were exploited terribly. Five years after the union arrived, workers' wages had risen 32%. Labor unions are one form of political power, and political power is worth money. It can be eaten - it was worth 32% of their former wages. The second question is whether the boss suffered after the wages were raised. Did profits drop? In those Zaozhuang mines, profits did not drop.
I've asked two bosses what would happen to their companies if, in the next five years, their employees' wages were to rise 30%. Would they forfeit market competitiveness? They said that the competitive edge that China has in the world market, particularly its cost advantage, is not just a point or two.
Today, Chinese products can be dumped on the world because of that labor cost advantage. This upsets workers in other countries, and has even caused problems to international order.
I've calculated that if China were to increase the salary of its 100 million migrant workers by 32%, this would bring to their families benefits worth 5 times what canceling the agriculture tax brought. This money would be transformed into spending power. One problem China has today is overproduction. Even if its competitiveness on the world market is weakened, the benefits of spurring domestic consumption are enough to make up for it.
