With renewed participation in recent years of the United States in the World Heritage Convention (specifically, nominating of sites for the World Heritage List even as the US has withheld dues payments from UNESCO and the World Heritage Centre), the economic benefits of World Heritage designation are coming into focus.

A recent editorial in a local paper promotes the economic benefits of World Heritage designation and the popularity of US National Parks in calling for increased funding for maintenance and management.
