It's easy to think of ways the federal government could be reduced right now, and a recent book from the Cato Institute catalogs many of them in the hopes that lawmakers will see the light.
The question is, why would politicians ever reduce the power they've worked so hard to seize? The only reason would be because the people whose votes they need are demanding more liberty — which mostly people aren't, at present. As a result, I suggest in my review of the book for The Freeman, projects such as Cato's are well-meaning, but misguided. Education — for the Remnant, not politicians — is liberty's, and civilization's, only hope.
