When the law came into effect the was hope that it would provide a source of much needed income to Native American communities; in a few cases this has also come true.

In addition clever businessmen have frequently established joint ventures with tribes on terms that have left meager funding for Native Americans. There are also examples of small groups of people with dubious Native American heritage who have been able to register a tribe solely for the purpose of establishing a tax exempt casino.
