“If you stand on the steps of a state capitol building and throw a rock (with a really strong arm), the first building you can hit has a good chance of being the headquarters of the state teachers’ union. For interest groups, proximity to the capitol is a way of displaying power and influence. The teachers’ union strives to be the closest. It wants to remind everyone that it is the most powerful interest group of all.” –Jay P. Greene, the Endowed Professor of Education Reform at the University of Arkansas
