I have one final thing: it is that 83% of unions reported that staff members were required to spend more time on compliance and less time on other duties.
In sum, I would say, when you ask who has benefited, more burdensome reporting requirements have not benefited the public interest. They have not exposed cases of corruption or made union officials more accountable to their members. They haven't advanced the cause of transparency. However, they have wasted public money and they have politicized regulatory enforcement in the United States.
I'd be happy to answer in more detail questions about any of these issues.
