The head of the Utah Taxpayers Association is Mr. Howard Stephenson. He is a state senator for district 11 (Salt Lake County). His role as a senator is to represent his constituency in the state senate and to enact legislation in our behalf. This is only a part time role and most, if not all, state senators have other full time employment. As a state senator, he receives $28,308 (see http://utahsright.com) in pay and benefits. It can be assumed that as the top dog at UTA, he is paid significantly more than that from the UTA (perhaps many hundreds of thousands annually or more). It's anyone's guess how much that is, because it is not public information.
Now, it's one thing to make a lot of money as a businessman, an entrepreneur, an investor, or another politically agnostic profession. However, the UTA has a stated political agenda. Obviously, this presents some form of conflict of interest in that he is likely to promote the agenda of his employer over that of his constituents. It would be illegal for him to take money directly from lobbyists, companies, or other entities trying to push an agenda through the legislature. However, there is nothing illegal about doing this if the form of payment is a salary from your employer, even when your employer publicly pushes an agenda. Despite being legal, it is highly unethical, and it is surprising that there is not legislation prohibiting this. Oh wait, these are the legislators we're talking about. Perhaps that explains it.
