Unions are a dreadful thing in any society. No, not the kind of unions which, in return for dues, simply provide legal service and help people save up for holidays and bridge the financial gap between jobs, but the kind which is sheltered by the State and is legally, although immorally, allowed to use force and violence against employers.
Here is a useful quote:
"Those who tell you of trades unions bent on raising wages by moral suasion alone are like those who would tell you of tigers that live on oranges." The result of union activity, therefore, is to reduce the number of jobs in an industry and to raise the money wages of union labor, while at the same time relegating many workers, driven out of this line of work by the decreased quantity of labor demanded there, to other lines of work, whose money wages must decrease as a result of the greater supply of workers now forced to compete for them. (#)This shouldn't be a mystery to any rational thinking person. Unions are a kind of price control, distorting the relationship between supply and demand. By increasing the price of one group of workers, they decrease the price of everyone else. By using law and State-force to uphold a manipulated price of one kind of work-labor, thereby decreasing the demand for it, all other workers must suffer with lower prices for their labor, since it is now artificially higher in supply.
The lesson? Abolish State-protection of union-activity, and returning to the time when "real wages in manufacturing climed an incredible 50 percent in the United States from 1860-1890, and another 37 percent from 1890-1914", and that's it.
