America's relatively open immigration policy makes this country better off than many other developed lands whose governments also must fund the pensions and health care for growing numbers of retirees. Yet there's still a huge need for more productive and skilled people, both current residents and immigrants, who will produce enough goods and services to provide for their own needs and for those in retirement. Otherwise, entitlement spending eventually will touch off intergenerational warfare.
Granting permanent resident status to foreigners who buy houses in this country will curtail a primary driver of the deepening recession and financial crises -- excess house inventories and the resulting collapse of prices. Since the people who will buy these houses will tend to have money, education, skills and entrepreneurial talents, they will be substantial assets to America in both the short and long runs.
