DAVE KOPEL: Is the tax power infinite? “Americans today are not bound to meekly accept the most far-ranging assertions of congressional power based on large extrapolations from Supreme Court cases that themselves come from a short period (the late 1930s and early 1940s) when the Court was more supine and submissive to claims about centralized power than was any other Supreme Court before or after in our history. American citizens, in the political process and in their personal lives, will ultimately have the final word on the Constitution.”
