Unions sound great in theory, but they aren't working all that well in practice for high-paying fields that require specialized knowledge. It negates the main advantage of that: being able to move between jobs without losing the salary, because employers are paying _you_ for your skills. Unions also are terrible because they often artificially strangle the supply. For example, you can't become a licensed electrician without completing an apprenticeship, and unions control the number of apprenticeships. With all the corruption associated with that.
