So, I am in the odd (and uncomfortable position) of perhaps agreeing with Thomas Friedman. I did not read his recent editorial (in fact, I have not read much of the man since The World is Flat), but he was referenced in a provocative posting - Immigration is Key to Entrepreneurial Economy.
The blogger speculates that the "problem" of immigration may be self correcting, if the government continues the "war on immigration". He writes:
The primary reason that we see so many immigrants pursue entrepreneurship is that they are opportunity focused - surveys reveal that this is what drives many of them to leave for new a new country. I have to wonder how attractive the US will look in a few years after our mad dash to socialism is fully in force.
