Perhaps the stability of the Midwest and a culture unlike Silicon Valley where folks move jobs every two to three years. There does seem to be more loyalty in IL, and the calmer pace may encourage more long-term planning?

Honestly, I spent most of my life in Chicago and only recently moved out to the Bay. I can't say in a major metro like that there is any more inherent loyalty. In many industries the only way to get ahead is to change jobs every couple years to make sure you stay at market rate for compensation.
