Not to mention that there is a difference between unions and the AMA, NAR and NADA. Those groups lobby to impact policy they do not negotiate for salaries and benefits for their groups. Further the AMA lobbies for policy that impacts medical care delivery to people. NAR looks to impact housing policy and the availability of financing for homes. I’m not saying they don’t so please enlighten us as to how each of those unions does anything in the name of the general public?
