I plead busyness for forgetting to have read Cato Unbound's August discussion on Mexican immigration since August 20, but I'm now caught up. I particularly liked Stephen Trejo's essay. My position on immigration has been softening for a while now. My policy preferences on border control haven't changed much, but over the past few years I've moved from having at least some sympathy (however short-lived) with Samuel Huntington's views to sharing Trejo's informed optimism about long-term assimilation of Mexican Americans.
