Many Iroquois have been fully integrated into the surrounding Western economy of the United States and Canada. For others, their economic involvement is more isolated in the reservation. Whether directly involved in the outside economy or not, most of the Iroquois economy is now greatly influenced by national and world economies. The Iroquois have been involved in the steel construction industry for over a hundred years, with many men from the Mohawk nations working on such high-steel projects as the Empire State Building and the World Trade Center.
