However, you must take the uniqueness of the person and the group he's a part of into account. People don't have the same backgrounds, interests, talents, or cultural experiences. Because of that, nothing could be more foolish than to treat every person as if he's an interchangeable widget that should fall into some statistical category to make a bunch of bean counters in D.C. happy.
Most nations are interested in what's good for them: The only thing liberals love better than big government is even bigger government. So, yes, they love using the power of the federal government, but they're even more in love with the idea of building up the United Nations or some other form of world government.
Setting aside the fact that the bigger government gets, the less efficient it becomes, there's another huge problem with the United Nations: it's comprised of individual nations that view the organization as little more than a way to further their own interests, which may oftentimes be in conflict with those of other nations.
The truth is that most people and most nations are primarily interested in taking care of Number One. Moreover, those that don't think that way and feel strongly enough about it to take action beyond a few platitudes or token contributions are few and far between. So since that is the case, any nation that doesn't have strong safeguards for its own national interests in any sort of deal it enters into with other nations or groups of nations, is extremely foolish indeed.
Most of the world operates by the law of the jungle except when they fear the consequences of doing so: Ann Coulter once said that, "the natural state of the world is Darfur. The freakish aberration is America and the rest of the Anglo-Saxon world." Throughout much of history, the idea that most of the world operated by the law of the jungle was so self-evident, that few people doubted it.
However, because the world's only Super Power is a benevolent force that has worked very hard to keep global conflicts to a minimum despite getting very little credit for its actions, many people allow themselves to believe that the world is a relatively ordered and civilized place. That's not so. The prosperous and democratic nations of the world may not have any designs upon their neighbors, but most nations are neither prosperous nor democratic, and the only thing stopping them from taking what they want by force is their inability to do so.
The federal government is by its very nature, slow, stupid, expensive, and inefficient: There are always politicians promising to "reform government" or "make government work," but the federal government always has been and always will be a poor, misshapen tool compared to the free market.
That's because their money isn't on the line and they don't go out of business when they fail. So, the more we keep the functions handled by the federal government at an absolute minimum, the better off we will tend to be as a nation.
Every problem is not fixable: The poor? They are always going to be with us. War? It's always going to exist. Inconveniences and annoyances? We're never going to live in Utopia -- not on this earth anyway.
That's not to say government should never try to help the poor, avoid war, or make a more perfect society. Again, let me repeat that: that's not to say government should never try to help the poor, avoid war, or make a more perfect society. However, there is also something to be said for letting sleeping dogs lie and just accepting that the government cannot and should not try to fix every problem.
That's because not only is it impossible to fix every problem, but because the government's efforts are usually ineffective and often as not, over time, it simply ends up creating a new set of problems to be solved.
