Just a bit of food for thought.
Most arguments over government, aside from the loud and senseless ones by those cheering for their political team, end up about how much government is the right amount of government.
Socialists, be they communist or fascist, think the government should control just about everything. Communists run the government and their countries with political party elites, fascists run it with a few political elites and large business leaders. Libertarians and anarcho-capitalists by contrast think little or no government is just about right.
We have seen socialist extremes in our life time, Russia collapsed under a huge central government. The American Revolution came close to a libertarian society, a limited and weak central government with free and separate states competing for free and mobile citizens. There have been no extreme anarcho-capitalist states since the Industrial revolution. Prior to that the Hansa League for one was a type of very loose capitalist alliance, for centuries there was no real central authority structure.
States in transition to watch include China, now capitalist in structure with a strong central government growing weaker. The United States is also in transition, it was once capitalist in structure with distributed power and since the start of the last depression has steadily been socialized and centralized. Russia, stuck in the spin cycle. Russia has never had a strong small business class, the closest it has come to capitalism is fairly primitive. Russia is floundering about with half measures and over reactions. India is the unnoticed but potentially powerful dark horse, a large number of literate people strangled by regulation and tradition, but they are emerging quickly.
The oldest democracy in the world is Switzerland, with over 500 years of successful decentralized government among diverse citizens. As a capitalist country surrounded by a heavily socialist Europe, Switzerland too is under great pressure. With the emerging information and miniaturization age all countries are under the pressure of societal change.
When folk talk of programs they feel absolutely need government, they usually mention at least roads, courts, and police.
Roads we can envision privatized because we have seen toll roads. Courts are tougher, but we have seen Judge Judy. JJ is really just binding arbitration, both parties guarantee they will abide by her decision, a quick presentation and the case is settled. Most civil matters can be privatized, and then we can look at criminal trials.
Police, here we can consider small private teams of Cops looking for a few year contract. Their reputation for lack of unnecessary force and fair action may get their contract renewed, otherwise they can get booted. The threat of the boot, and the extra pay from competition for the better teams, will encourage fair and balanced enforcement. Police as short term mercenaries under civil authority is very doable. Think of it as term limits for power.
The Libertarian Harry Brown said something to the effect, "Would you give up your favorite government program to stop paying taxes?" Think of the huge outpouring from the private sector for Katrina, private charity is much more efficient than government, and would be larger still if government did not take half of everyone's income.
It can be done. The question is with our changing society will it be done? The next question is who will attempt it first? There will be the potential of wealth for the people of any countries that succeed.
This next 50 years will be very interesting.
Judge Judy, one way to avoid slow courts.
