Well, from Wiki-
Des Moines is a major center of the US insurance industry and has a sizable financial services and publishing business base. The city was credited as the "number one spot for U.S. insurance companies" in a Business Wire article and named the third-largest "insurance capital" of the world. The city is the headquarters for the Principal Financial Group, Ruan Transportation, TMC Transportation, EMC Insurance Companies, and Wellmark Blue Cross Blue Shield. Other major corporations such as Wells Fargo, Cognizant, Voya Financial, Nationwide Mutual Insurance Company, ACE Limited, Marsh, Monsanto, and Corteva have large operations in or near the metropolitan area. In recent years, Microsoft, Hewlett-Packard, and Facebook[8][9] have built data-processing and logistical facilities in the Des Moines area.
I think there is "value that the eyes of the Execs" there.
