There is a big difference between "bargaining in good faith" and being "extorted". If companies treat their employees decently and provide them with acceptable wages and benefits then there is no need for a union. Oil companies are a good example. They provide an acceptable wages/benefits package, they are therefore non-union. And I'm not a big fan of Big Oil, I only use that as an example. The flip side to that are the companies that refuse to recognize that their employees are their greatest asset, those employees are what has allowed that company to survive and prosper. There is always a happy medium, but it always involves give and take on both sides to find that sweet spot that everyone can live with.
