If diversity perceptions were a key driver of the economy, California would have low unemployment and strong growth. Instead, it's losing businesses hand over fist due to high taxes and burdensome regulations. Oklahoma has one of the lowest unemployment rates in the country. Quality-of-life issues clearly matter for employee recruitment, but to argue that those making relocation decisions give greater priority to a perception of “diversity” than concrete business considerations is absurd.
Ultimately, Oklahoma's future economic growth relies on entrepreneurs who focus first and foremost on making a profit. If a company executive isn't locked in on that goal, state officials shouldn't waste much time trying to convince that person to set up shop in Oklahoma. They're probably not going to be in business for long anyway.
