A liberal thinks the economic "pie" is finite because they are socialist thinking and believe it can never grow. A conservative, on the other hand, believes that through free market capitalism the economy can continue to grow and the wealth spreads naturally, hence the pie gets bigger and bigger as people work, invest and grow their businesses. The greatest killer of "pie-growth" is to adopt the values of a liberal's economic principles. By the way, the most effective "stimulus" is for each American who pays taxes be allowed to keep more of the money earned. Money in the hands of millions of Americans across the land that they have earned create a great boon to the economy when they spend it on products and services.
