This always comes up when unions in America are blamed for these problems. Unions are strong in both France and Germany and they don't have most of these problems.
The answer is corruption. America is horribly corrupt, much like Latin American nations, and unlike western European nations. So unions in Europe actually work the way they're supposed to, whereas in America they're just another corrupt institution, probably much more corrupt in fact than most others, and cause more problems than they solve.
How do you get America to have unions like those in Europe? I have no idea, but I think it's like asking how you can turn Afghanistan into a country similar to Norway.

Easy. Allow the employee to pick the union - you can have more than one union per employer. Or no union at all if that's what the employee wants.
That's the only change needed.
If like, add a second change: It's not longer necessary to make an employer be a "union shop" any employer can have employees represented by unions, if that's what the employee wants.
