She's not right. She has an opinion. Don't confuse opinion and right-wing political belief with fact. By the way, I've never read a business or economics textbook that specifically said anything bad about unionism. If there is one out there, it is horribly slanted, presenting opinion as fact, and should be removed from the shelves. If it was fact, there would be no such thing as a left-wing, democrat economist. It's a difference of opinion with very valid arguments on each side of the issue; not something that can be directly quantified and proven as fact. Each side of the issue can work the numbers to show the validity of their argument.
