Earlier quoted context omitted.
They're not the same. Unions are equivalent to crony capitalism (ie. regulations put in place to prevent competition), but most of what companies do is just free markets at work (which helps the consumer).
How is a union a regulation? A union is a contractual obligation between workers that they will only work under certain conditions.
In what country? In the US, most are mandated by law. All government jobs are union, regardless of the wishes of the worker.
Contracts are mutually consented to. If it's a union job, you have to be a part of the union. How is forcing workers to do something they do not want beneficial?
I'm all for unions where someone can join and leave freely without the threat of force or loss of work. Do we have that in the US? No.
