I'm coming to the party a little late on this one but was interested by this story.
The trend is even starker if you go back a decade earlier. In 1960, 31.9% of the private work force belonged to a union, compared to only 10.8% of government workers. By 2010, the numbers had more than reversed, with 36.2% of public workers in unions but only 6.9% in the private economy.No such check exists in this scenario. The consequences are even more extreme when the normal realities of the marketplace are removed from the equation.
unlike in the private economy, a public union has a natural monopoly over government services. An industrial union will fight for a greater share of corporate profits, but it also knows that a business must make profits or it will move or shut down.
