High Quality Content by WIKIPEDIA articles! Opposition to trade unions comes from a variety of groups in society and there are many different types of argument on which this opposition is based. Milton Friedman, Nobel Prize winning economist and advocate of laissez-faire capitalism, provided evidence that unionization frequently produces higher wages at the expense of fewer jobs, and that, if some industries are unionized while others are not, wages will decline in non-unionized industries. By raising the price of labor, the wage rate, above the equilibrium price, unemployment rises. This is because it is no longer worthwhile for businesses to employ those laborers whose work is worth less than the minimum wage rate set by the unions.[4] As such, Governments may seek to reduce union powers in order to reduce unemployment.
