Here's an interesting illustration of the law of unintended consequences, a law that seems to attach like velcro to liberal legislation:
At the time, it was common for Aborigines...to work in the Australian cattle industry as cowboys etc. They were however viewed as unreliable employees (principally because of their custom of "going walkabout" (decamping) at unpredictable and inconvenient times) and were paid less than white employees. It was however one of the few employment avenues open to many of them because of their low levels of education etc.
Subsequently, empoyers were forced by law to pay Aborigines at the same rate as white employees -- thus bringing to an almost total end Aboriginal employment in the cattle industry. They are now heavily dependant on welfare payments from the Federal government.
What makes this piece of social engineering especially pernicious is that the judges who handed down the equal pay ruling said at the time that they knew that the Aborigines were less valued employees and that the ruling would throw most of them out of work.
Nevertheless, they chose to consign the Aborigines to abject penury in order to save them from the "injustice" of an unequal wage scale. Classic. In order to satisfy the liberal hunger for socio-economic egalitarianism they made a bone-headed ruling that they knew was going to harm the poor and help them not at all. This is a fine example of piling malevolence on top of stupidity in the name of ideological principle.
