John Stossel‘s latest column presents a different take on the state of the union than the one the president put forward Tuesday night.

Has Barack Obama learned nothing in three years? Last night, during his State of the Union address, he promised “a blueprint for an economy.” But economies are crushed by blueprints. An economy is really nothing more than people participating in an unfathomably complex spontaneous network of exchanges aimed at improving their material circumstances. It can’t even be diagrammed, much less planned. And any attempt at it will come to grief.

Politicians like Obama believe they are the best judges of how we should conduct our lives. Of course a word like “blueprint” would occur to the president. He, like most who want his job, aspires to be the architect of a new society.

But we who love our lives and our freedom say: No, thanks. We need no social architect. We need liberty under law. That’s it.

Obama — and most Republicans are no different — doesn’t understand the real liberal revolution that transformed civilization. The crux of that revolution is that law should define general visible rules of just conduct, applicable to all, with no eye to particular outcomes. In other words, as Nobel laureate F.A. Hayek taught, the only “purpose” of law is to enable us all to pursue our individual purposes in peace.
