Although you can block unwanted phone calls from commercial sources, you cannot block automated phone calls from politicians, which will be inundating us this election year. Apparently the courts think that the right of "free speech" includes the right to impose that speech on an unwilling audience. Maybe we need a new Constitutional Amendment, guaranteeing "freedom from speech."
I already have that freedom, which I excercise on a regular basis by hanging up. It requires less effort even than slamming my front door in the face of a candidate's volunteer. Other than that, it was a fine article. Sowell is someone I could definitely vote for.
If I might add slightly to the threadrift, good stuff from Walter Williams can be found here:

http://www.jewishworldreview.com/cols/williams1.asp Government income redistribution programs produce the same result as theft. In fact, that's what a thief does; he redistributes income. The difference between government and thievery is mostly a matter of legality. Browning's solution is captured in the title of his last chapter, "Just Say No," where he proposes, "The federal government shall not adopt any policies that transfer income (resources) from some Americans to other Americans." He agrees with James Madison, the father of our Constitution, who said, "I cannot undertake to lay my finger on that article of the Constitution which granted a right to Congress of expending, on objects of benevolence, the money of their constituents."
