If 40% of the workers are not part of the union, seems that you are free to be part or not of the union. And that the union makes sense to the worker, as more than half of the workforce choose to join.
Money helps, but union main strength comes from number of member and support. So paying for it or being member is in all case 2 very different things. And it seems workers are free to join or not, and most of them decided to join.
I don't know the situation of all European countries, but in France, unions gets some money from their member, but they also get some money from the state (ie taxppayers), and some elected union/worker representatives have some work time paid by the company to work on workers representation and union stuff
Perhaps am I ill informed (never been in USA, and my friend living there are not in unions), could you give us some sources saying that what you say is the main form of union in USA today ?
