I like James Buchanan's perspective on governmental overreaching and the message of public choice theory:
A central message of public choice theory tells us that if politics generates undesirable results, it is better to examine the rules than to argue about different policies or to elect different representatives. Well and good. But those of us who have peddled this message have been too reluctant to get down and dirty with proposals for constitutional change. Hence, I felt challenged by the editor’s invitation to propose three specific amendments.
As many have observed, for better or worse, there isn't a lot of difference between our political parties... both want to spend us into bankruptcy, and neither is willing to leave us alone. Public choice theory says that the solution isn't to vote for different people (who will continue to let us down) but to change the rules of the game by, e.g., amending the Constitution.
Mr. Buchanan goes on to describe three amendments he favors, so I figure it's worth linking to one I have advocated for years: the Sunset Amendment, which would prevent Congress from passing any law that would stay in effect for more than six years.
