Henwood on immigrants

Doug Henwood's Left Business Observer is always an exceptionally good read. Though it's mostly a print publication (so consider subscribing), there are some articles available online (here) which give a taste of the quality of LBO.
For the moment I'd like to call your attention to a new article on the LBO site, A nation of (yesterday's) immigrants. If you are at all curious about the economic effects of immigration (at least as it pertains to the US), it is a must read. He briefly trots out the evidence:
-Several "natural experiments" involving sudden mass immigration (Algerians to France; Cubans to Miami; Russians to Israel) show that immigration has no significant effects on wages or employment levels.
-Far from sucking the system dry, immigrants on average pay more in taxes than they will ever use in services.
-Immmigrants' children, no slouches themselves, tend to get more education and earn more than their native-born counterparts.
The article finishes is with a very interesting graph which charts Americans' attitudes toward immigration since the 60's. Very much worth examining.
