“If limited government is what you’re after, neither political party is your friend, since government expands under both. What’s more, the rate at which it expands depends less on which big spenders are in power than on whether we have divided government.
For evidence, consider President George W. Bush’s presidency, when, for a time, Republicans controlled both the House and Senate. During that time, we saw the creation of a new department (Homeland Security) and of a new entitlement (Medicare Part D), and spending exploded. We didn’t see any restraint during the two years when Republicans were fully in control under Trump, either. Further data confirm that unified government does not keep government restrained, even if the controlling party is supposedly the enemy of big government.
Divided government, on the other hand, encourages more restraint, no matter who is in power or who controls which branch of government. Divided government doesn’t stop the government from growing; both parties are always happy to spend more money on defense, infrastructure, and education, just to name a few favorites. However, the Democrats tend to limit the Republicans’ hunger for wars, and Republicans prevent the worst of Democrats’ fantasies about foisting greater government control on the economy.”
“the incentives for good management in government are very weak, because politicians make decisions using other people’s money. As a result, their exposure to the risk of a bad decision is limited, while there’s rarely any reward for spending taxpayers’ money wisely or providing a service more effectively or efficiently.
Furthermore, each individual voter bears a very small part of the costs of bad government decisions. Politicians can thus shower special interest groups with subsidies at our collective expense, grant costly tariff protection to politically powerful producers, and generally waste our money for their individual political advantage.”
“In politics, decisions aren’t driven by the profit motive like they are in the marketplace. Instead, they’re overwhelmingly driven by the desire to get reelected. Special interests can help with that. In fact, public choice economists have shown that government officials receive more benefits when they act on behalf of special interests than for the public good. This finding doesn’t depend on who is in power.”
