>Certainly the awesome political power they wield hasn't helped to increase salaries (compare them to any other credentialed profession requiring a college degree), or prevent charter schools from eating away at public school funding, or to restore some of the pension benefits that were taken away in the eighties.
I cant speak for the nation at large, but this doesnt track with my experience in california.
Public school funding has massively increased. It has gone from somewhere around 9K/student in 2012 to $24k/student in 2023. With an average class size of 29, that is $700k per class per year.[1] They are rightly scared of charter schools and private school vouchers.
California teaching is a decent profession on average, but compensation is extremely seniority based, with senior teachers payed 2X new hires, while doing essentially the same job (~$50k vs $100k) .[2] this is an internal struggle that most US unions have. Based on US union law, there is one union while in Europe employees can shop between multiple. As a result, US unions suffer from a tyranny of the majority which will sacrifice minority member interests for that of the majority.
I have a friend in a public utility union where the union fought against WFH for IT workers, simply because the field workers were jealous.
