Anyone with a modicum of life experience, shoiuld not be so naive as to think for one moment that either big business or unions are any paragon of purity. Both are constructs of fallen man and thus subject to all the faults of fallen man; such as greed, hunger for power, ego, corruption. lying etc.
First, the business bosses took advantage and exploited the workers. Then, and rightly so, workers united in self defense and improved their lot. Then the unions started selecting all-powerful union bosses; carbon copies of those they were taught to hate; the big business bosses.
Some union members were bright enough to see this progression long ago, and divorced themselves from it ! Others figured they wanted revenge on the big business bosses, or "tyrants" .... and thought " our big union bosses are OK...because they are OUR big bosses, or "tyrants" !
In recent years, unions, operating on an international level, have assumed too much and have resorted to economic, mob and occasionally, physical terrorism...against those corporations or even individuals who do not want to join their club or take their orders from them.
Bad enough, when these tactics are resorted to when dealing with private or shareholder corporations; however when these extortion tactics are used against the taxpaying public, Unions have gone a bit too far !
...And that's exactly what the mob scene in Wisconsin is all about !
