Sumit,
Lets come down to the practicality of implementation of your ideas. You have talked about privatising everything from education, road building, military, etc. with no government at all. So, lets take military first..
How exactly will a privatised military work in your world? Will people have a choice to pay tax to support that military? What if out of total 1 billion people, only 2 lakh people want an army or actually pay for it if they have a choice. How will you support that army?
As far as military is concerned, I want the world to move towards the direction of total demilitarization. No country shall have a weapons development program. Weapons companies like Boeing and Northrop-Grumman will be closed down because there wont be a market for the products.
But, lets talk reality. You know and I know that it is never going to happen. Some rogue regime like North Korea is not going to stick to such regulations.
Right now, defense from big weapons (Atomic Bombs and ICBMs) is a monopoly held by the government. If you go through the link for the paper that I attached, you will see that there is so much wastage of funds even by private contractors like Boeing, because they do not operate in a free market scenario. They get any amount of money from the government as long as they deliver what the government wants.
If this monopoly is broken and private players are allowed to enter this market, trust me it is a huge market that many companies would be willing to invest in. But, presently private investment in national defense is not allowed by the government.
Private companies would do business more efficiently and will provide better services due to competition. We could have contracts like say for example for 5 years a company provides defense from Nuclear weapons. Just like people have insurance policies, they could have such services. In case the private defense company is unable to secure us from a nuclear attach, they will have to pay damages as mentioned in the contract. If you die in the attack, then the proceeds go to the person mentioned in your policy.
Just like insurance companies do not cover those who dont buy their policies, such companies wont be responsible for those hurt by such hostilities who did not pay for their services. So, such services could work just like insurance policies.
Would these services work? Heck yea they will! If the government wrapsup the military, whose going to protect me? There will be a demand for security. And that is the beauty of free-markets. Where there is demand, there is an opportunity. I will sign up for the best defense agency that my money can buy.
This whole concept is very fluid as of now. But, it could come to shape if the government let it be implemented. Dont forget the invisible hand concept by Adam Smith. The invisible hand is behind all the developed fairly capitalistic economies of the world.
If the invisible hand worked everywhere else at promoting the economic welfare of the people, why do you think it wont work with National Defense?
Now dont say that such Private Agencies would attack us and colonize us. Well, do not forget why colonialism failed. Colonists like Great Britain realized that they could benefit even more by having a free market system than by stealing the physical wealth of other countries. Trust me, if Britain had the will, we would still have a Union Jack on the Red Fort.
Such defense agencies face competition from other defense agencies. If one of the screws up, they will be out of business in no time and replaced by a more sincere and honest service provider.
Lets say roads are built by private companies only if people pay. Thats obvious coz there would be no government so nothing can be forced upon people even if its for their own good. What if in my locality, only half of the people agree to pay for a new road, will the road be built by other half's money? Also, there will never be a road in the villages coz villagers will never be able to pay for a road to the private companies who will only work for their profits. So, how will the development happen in rural areas in your everything private society.
Do you think there is a demand for good roads? I gues the answer is yes. So why wont people pay for better roads.
And, why wont a person pay for the road in his or her locality that he or she needs to use?
When you go to a grocery store and you want a loaf of bread. The only way you can have it is if you pay for it. Lets assume that you wont steal it. If you dont pay for it, you cant have it. What will you do? I guess you will pay for it, or you will sleep hungry for that night.
So why wont people pay for roads? Under the current system, a lot of people are not paying for the bread and having it too. Dont you think it is unfair?
We need a system where people pay for the goods and services and get a certain expected level of quality in exchange. A system where there is a recourse in case we do not get what we pay for.
There is a toll-road between Noida and Delhi (where I am from). You have to pay 10 rupees (thats what it was 5 yrs ago, dont know what it is now) to use it one way. Man, that is the best road you would ever get to use in Delhi. And guess what, people pay for it.
Initially people were cautious and would say: whose going to pay 10 bucks when they can taken an extra 15 minutes and use one of the two other alternative ways to get from Noida to Delhi. But they were all proven wrong.
From what I know, it is a highly successful venture. The invisible hand was at work again.
If people would pay the toll for the Noida-Delhi road, even when there are other free alternatives, why do you think people wont pay for such services elsewhere.
Especially, if there a road outside my house that I need to pay for to get to work, I will pay for it. And if there is a pot hole, I can stop paying for the road until they fix it. It could all be in a contract that specifies a certain quality of roads, otherwise the clients would be exempt from paying until the problems are fixed.
Once my land line was dead for three days. I called my telephone company and they fixed it. Guess what. I got a credit for the three days that I did not get the service even without me asking for it. Would MTNL give you credit for absence of service, when phones are dead for days at a length?
Ofcourse, there will be roads in villages. Dont people in villages need roads? Wherever there will be a demand for roads, there will be roads. They wont build a road to Mt. Everest, because there is no demand for it.
But, there was demand for space tourism. So, Sir Virgin Atlantic will be starting space flights in 2008. That is the power of free markets.
You have to think of the whole concept of free markets with an open mind. Just think of it this way. Free markets give the power to the consumer who can choose the best service for their money. And if the provider fails to meet the expectations, it will be punished by free markets by shifting its business to other providers who will provide better services for the money.
The government does not want you to imagine the possibilities of free markets. Because, if it looses its monopoly on services like roads and defense, then it will loose control. People do not join the government to serve the country. They join the government to gain power and control. Whether it is an IAS officer of an elected MP. It is all about power and control.
Free markets will take this power and control from corrupt despotic leaders and put it in your hands.
