Every country, defined by its constitution grants some "Civil Liberties" to its citizens, which it protects economically, socially and politically with its strengths. This, of course is a give and take transaction, you lose something (taxes, etc.) to gain those Civil Liberties. However, one can infitely argue that most of the Civil Liberties of one individual can clearly be used to violate those of another individual and by that render the constitutional protection invalid.
Furthermore, another state (say Uncle Sam) can be feeding false information to citizens of another nation. Hence, even though the Liberty of right to information is available to a citizen of another nation (say Iran), they might be willing to remove it from their citizens in order to truly protect them and the belief systems.
"The Republic" has wide arguments as to why an ideal state cannot be constructed; while many of those who have read it believe it to be a model for a state. I consider Plato a cynical commentator; who never laid out plans. You might think otherwise, but remember Timmaeus and his two references to Atlantis and you would really think of a reason to agree that he is indeed a cynical commentator.
So laws, constitutional freedom and whatever is offered with the citizenship of a country appear to be a simple contract. Something, that's as good as one you make with your employer. Only, a great deal more complicated covering far more serious issues including conditions under which all your liberties will be revoked, so on and so forth.
I had once read a paper (intending to write a book) on futuristic scenarios researched by the US military. One of the scenarios was about a unified world where corporates ruled. The other was a pangea kind of idealistic scenario, while the last was a oligopolic, Tristate power and space sharing thing. I believe today's world is already an oligopoly requiring alignment to one side or the other. It's just a matter of the contract agreement, the give and take. There's one big difference, countries tend to be far more immoral than any corporate and can go to any level including destruction of all civil liberties (including the right to live.) If you're thinking I'm crazy why not try www.contactsingapore.org.sg and find out how you can "buy" a citizenship in this rather small-sized city state.
There are enough companies and organisations who already have casteist, linguistic or ethnic requirements other than technical requirements that they normally post on a job notice. Citizenship seems no different. Nativity is not always a guarantee of citizenship unless there is a huge chance that you will be brought up in the same country within their belief systems.
Through the looking glass, things seem far more lucid than the fairy tale world that the media presents on my idiot box. We already live in a corporate world, where almost all rights are a give and take. There are no moral idealisms to dwell upon, only real contracts. Not all these contracts and rights are monetary, making some idealists dwell within their delusional schizo-matrices. After the creation of Rome there was no turning back.
It is better that we agree and understand that nations, patriotism, nativity are just catch-phrases in a world built on contracts (give-and-take.) We can stop talking about morality, flawed laws, corruption and look for the best CEOs to handle India Inc., Sri Lanka Inc., Thailand Inc., N.Korea Inc., so on and so forth. Everyone must understand that idealist patriotism and believing in a nations religious alignment, so on and so forth are mere facades screening the truth behind it. It's true, I finally see it, we are living in a world of mirages and illusions, the truth fortunately isn't bitter. We can make things better just by understanding where we are and what we are. It's the same steps you take within your organisation/company/school/university to try and make it a shade better that you can do with a nation, which merely is a much larger aggregation that might need a bit more abstraction to let the human mind "divide and rule" rather than be divided and misruled.
