Money Or National Pride?

Possibly the biggest motivator in building the fair was out-Eiffeling the Eiffel Tower. However, such a famous exposition as the fair is a great way to make money, as is evidenced by the skyrocketing land prices in and near Chicago, and Holmes's excitement in the news that such an attraction was coming into the area. Furthermore, the board in charge of the fair doled out prodigious amounts of money to seemingly everything and everyone that could help the fair. That seems to signify that Chicago(and the United States) had more to gain than simple pride. Money was most likely another major factor in the decision to hold such an exorbitant exhibit. Was money the primary motivator in the decision to build the fair, with national pride a necessary and beneficial side-effect? Or was it the other way around?
