The great thing about federalism is that it holds states up to the competitive test. If you become fed up with the failed policies of California or Illinois, you can head for Indiana or Texas.
If the central government in Washington, D.C. blows it, on the other hand, . . . you have a bigger problem.
Nevertheless, the days when you can lock up your citizens (like the old Soviets did) are just about over. If a nation’s leadership proves itself incompetent, it will have to add a mass exodus to its list of problems.
Folks have options. Especially the folks you might most like to keep on your team.
