Matt Lewis writes for the Week magazine that there is indeed a purpose for government:
When it comes to government, a lot of conservatives are probably too obsessed with size. Grover Norquist famously wants to shrink government to such a small size that you can drown it in a bathtub.
But I'm not sure most Americans want that. And trying to force it via draconian cuts doesn't work, especially if they don't address the specific problem, such as the need for entitlement reform. "You can't make a fat man skinny by tightening his belt," observed John Maynard Keynes.
Whether you're a conservative who cares about preserving law and order, or a free marketer who appreciates the importance the rule of law plays in providing confidence and incentives to entrepreneurs, you're a fan of government. Stop pretending otherwise.
