Despite the expansion of trade and investment achieved by the North American Free Trade Agreement, challenges remain. The most serious is the persistence of an income gap between Mexico and its northern neighbors. Unless this gap is narrowed, other challenges, including immigration, trade, and security, will persist. The solution is the creation of a viable North American Investment Fund, which will be possible only if the three governments articulate a North American Community and pledge to contribute, each in its own way, to a strategy that will close the income gap and build institutions to resolve old problems and address new opportunities.
