Most previous immigrants came to the United States to become Americans, with no intention of returning home. They relinquished their ties with their homeland. English was their key to prosperity, and they worked hard to master it.

The good news is, Americans know firsthand the benefits of a free market - more choices, lower prices, higher quality - and there is no reason why we cannot help them see these same benefits in health care.

Indeed, I think most Americans now know that in 1935 when Social Security was created, there were some 42 Americans working for every American collecting retirement benefits.

The reality is that the workforce relative to the number of people retired has shrunk and today in America there are only 3.3 working Americans paying payroll taxes to support each individual currently retired and collecting Social Security taxes.

For example, in my own State of Arizona, an Israeli scientist is working with an Arizona company on a demonstration project involving a very fast-growing algae which can be used to power a biomass energy plan.

If the United States is to protect itself from the economic and the political threats created by this excessive dependence, we must reduce our reliance on foreign energy sources and on foreign oil as quickly and as efficiently as possible.

Business owners have made a strong case to me that they need guest workers. But none has suggested that these workers should be placed on a path to citizenship.
