I didn't accompany this link from two days ago with any commentary, but I mostly agreed with the article, as some of you may have guessed. However, after reading this, I'm having second thoughts. Given the opportunity costs of making it hard for illegal immigrants to do things like get a job, get a checking account, take out a mortage, pay taxes, etc., I wonder if a more cost-effective way to reduce illegal immigration would be to take control of our southern border, as expensive as that would be.

Update: I should add that the costs to liberty also weigh in favor of border control.
