> Show me a well run union in the USA where they successfully compete against union union workers, their industry isn't being shipped overseas, and workers can optionally participate without having wages garnished.

Writers Guild of America East (for journalism), or the Authors Guild (novelists). You can become a journalist or a novelist without being a member. But both guilds have collective bargaining agreements with publishers.

>workers can optionally participate without having wages garnished.

This is the direct purpose of so-called "right-to-work" laws. Unions are required to represent employees regardless of whether or not they pay dues, meaning other members shoulder the costs of collective bargaining. This is called the "free rider" problem and is one of the biggest ones facing unions today. It's also one of the main targets of the PRO Act.
