I'm generally pro-union and certainly fair wage, but it's important to keep in mind that unions will grow into their own power centers and have leadership with its own internal goals which are not aligned with either their working members nor the employers.
Instead of repeating vapid arguments from the past 30 years designed to disincline people from joining unions, maybe you could look outside of your own borders and realize that it's not an inherent property of unions. Inherent to the US and your extremely unhealthy relationship with work, maybe.
You're not pro-union if you still spout anti-union propaganda. You spent more words arguing against unions than you did for them. I'd say your first part of the sentence is probably more of a rhetorical trick than anything close to true
but it's important to keep in mind that without unions the corporation will grow into their own power centers and have leadership with its own internal goals which are not aligned with either their working members nor the employers
