After a quick look at the UAW website...

Not really, probably NONE of this, because profit sharing wouldn't be part of gross monthly wages. $10-50 to join depending on the specific UAW chapter. Then it depends on the balance of the UAW defense fund. If it is at $850M or higher, 2 hours pay per month or 1.15% of gross monthly wages for salaried workers. If the balance is $650M or less, it's 2.5 hours a month or 1.44% for salaried workers until the balance is back to $850 million or more. And that Defense Fund is what they use during things like the recent strike to help members while they negotiate with the business.

It's still a significant net positive for the workers, meaning that the union gets the workers more money in their pockets than if there wasn't a union.

Your argument is therefore invalid

What is this saying?

Even if 99.9% of it went back to the union, you still made money and you'd complain about that? Like... What level of idiot math is this?

Are you the type of person who when given a free slice of cake, yell that you should be getting the whole cake?
