What the U.S. does right

Sorry for the absence, but a heavy work schedule has distracted me precisely at the worst possible moment.

To get on with it, there has been a huge amount published about immigration lately. One of the bes op-eds I've read has been by Fareed Zakaria, who convincingly argues that immigration is something the U.S. has gotten right compared to Europe. A must read. Key graphs:

Compared with every other country in the world, America does immigration superbly. Do we really want to junk that for the French approach?

The United States has a real problem with flows of illegal immigrants, largely from Mexico (70 percent of illegal immigrants are from that one country). But let us understand the forces at work here. "The income gap between the United States and Mexico is the largest between any two contiguous countries in the world," writes Stanford historian David Kennedy. That huge disparity is producing massive demand in the United States and massive supply from Mexico and Central America. Whenever governments try to come between these two forces -- think of drugs -- simply increasing enforcement does not work. Tighter border control is an excellent idea, but to work, it will have to be coupled with some recognition of the laws of supply and demand -- that is, it will have to include expansion of the legal immigrant pool.

Beyond the purely economic issue, however, there is the much deeper one that defines America -- to itself, to its immigrants and to the world. How do we want to treat those who are already in this country, working and living with us? How do we want to treat those who come in on visas or guest permits? These people must have some hope, some reasonable path to becoming Americans. Otherwise we are sending a signal that there are groups of people who are somehow unfit to be Americans, that these newcomers are not really welcome and that what we want are workers, not potential citizens. And we will end up with immigrants who have similarly cold feelings about America.
