Moreover, government can be more efficient than the market system. This is especially true for health care. The U.S. pays far more per capita than other industrialized countries but leaves tens of millions without coverage and lags in many measures of health.
Government provides real jobs and real services, despite regressives' common claim that only the private sector generates jobs.
Heck, without government we'd be hunter-gatherers: no laws, no sanitation, no commerce, no childhood immunization, no civil rights, no seat belts, and surely no Internet.
Government is like a computer operating systemThe best analogy for the role of government in society is the role of a computer operating system in a computer.
Without an operating system, your computer would be a useless hunk of metal and plastic. The operating system provides the basic rules, conventions, protections, and services necessary for the functioning of application programs such as editors, spreadsheets, browsers, and games.
Government plays a similar role in the functioning of a modern society. Government furnishes the rules, conventions, protections, and basic services necessary for the smooth functioning and interactions of businesses and individuals.
Sometimes computer viruses, spybots, malware, and other undesirable programs invade your operating system. They suck up resources, steal private information, and destroy data. To guard against such undesirables the operating system has protections, such as firewalls and security levels. Furthermore, you can install anti-virus programs that will scan your computer and protect you from suspicious programs.
In a similar way, government is sometimes co-opted by special interests who twist the rules, corrupt the lawmakers, and get laws written to their own benefit. Corporations, labor groups, teachers, government workers, rich people, poor people: everybody tries to make government serve their own interests.
One protection against government abuse is election finance laws. Publicly funded elections would make it harder for private interests to buy the votes of lawmakers.
Another protection is investigative journalism. Journalists are like anti-virus programs for government: journalists scan the actions of legislators and government workers, looking for wasteful or fraudulent behaviors. It is to society's benefit to fund independent investigative journalism, as well as to give tax incentives to privately run news organizations. The US spends a small fraction as much on public journalism as most other industrial nations.
Libertarian fantasiesLibertarians are right that too much government is usually a bad thing. Fascism is oppressive and Soviet-style Socialism is both oppressive and inefficient. But the only alternative to Socialism isn't laissze-faire capitalism. Libertarians like to imagine that individuals can thrive in modern society without the structure and guidance of a strong central government. This is idle fantasy. When the economy crashed a few years ago, corporations came running to the government to bail them out. Had the government not done so (preferably they would have bailed out homeowners, instead of the banks), we'd now be in a deep depression. Without regulations of complex financial markets, monopolies and corrupt practices would flourish, and further market crashes will be inevitable. Without the organizing role of a strong central government, commerce and trade would not flourish.
But, yes, we do need to beware of socialism in America --especially of socialism for the rich.
In short, society needs a strong central government as a brake on the excesses of capitalism and as a means for assuring the general Welfare.
The wisdom of the foundersIndeed, the founders crafted a Federal system, with a strong central government, because small-government society under the Articles of Confederation wasn't working well. (See this history.) The founders realized they needed Big Government to have a modern nation. The Constitution asks the Federal government to provide for the general Welfare and to do lots of other things to secure our safety and well-being.
The Preamble to the United States Constitution states
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
