Joint family is flawed institution

I do not call Joint family 'highly flawed' because it is not a hopeless case like arranged marriage. There are many good features of joint family but overall drawbacks are more. In any book of social science you can find these drawbacks listed there. I have nothing new to add to that list but I want to highlight some of them because my basic intention is to criticize one aspect of constitutional structure of India. When I thought about this aspect then I came to conclusion that widespread appreciation and practice of joint family is responsible for this.
So, I will start with problems of joint family. It is a socialistic structure. One person is head of the family and he controls everything. In joint family some people work a lot and some do not work at all but they all get same benefits. This breeds inefficiency. Controlling is the main problem of this institution. If control is weak then family will break, so a strong control on all the family activities is required. Controlling works against the personal development of most of the family members. It benefits one or two members only (many times the youngest member of the family as he is loved by all). Controlling kills the personal freedom which is needed for creative thinking. All these drawbacks you can find in detail in any social science book but still, I don't know why, people keep on appreciating this institution. Our hero in the hindi movies always advises the public not to break the family. Political and spiritual leaders keep on giving sermons in the favor of joint family. I want to simply say that all of them are backward looking and unscientific people.
Now I come to the main issue, constitutional structure of India. When India became independent, the makers of constitution considered joint family as holy cow and gave us the constitution of India. What is the problem with the constitution, it is the "Control". As in joint family there is a very strong head of the family we have a very strong central government. As in joint family, the members have very little say in crucial matters our state governments are powerless and resource less. Most of the states are functioning inefficiently and only few are working well. Today there are demands for many new states because people are fed up with inefficiency. Just making new states is not enough as we know they do not have power to function independently. We have lost a huge opportunity with 60 years of independence. India should have been a much more developed country by now, at least more developed than China.
America like constitution would have been much better for India. In USA the central government has only two things foreign policy and defense. Rest all is with state governments. In India our central government is running 5 star hotels and a junk, huge loss making airline named 'Air India'. They are doing hell lot of other loss making businesses so they do not have time for the most important thing , the defense of country. That is why we see terrorist activities happening at regular intervals. China is eating up our lands at border slowly. And there is no one to blame. When a farmer does suicide in Vidarbha the Prime minister is blamed in parliament. I think, like USA, our central govt. also should restrict itself with defense and foreign policy. Finance, HRD, Agriculture etc. all the ministries should be removed from centre. Indian railway is related to defense so that should remain with centre.
If we don't do this, many other countries (like China, Israel in the past 60 years ) will march ahead of India in the coming 60 years. We will remain many years behind them and will give them sermons on benefits of joint family.
