If you go to a country that puts its military on the streets and whose leaders have cults of personality, you realize US government is quite limited.
That’s also a misconception on your part; the deployment of armed forces is no longer in the hands of congress but whatever administration happens to be in power at that moment, its internal use always excused as a need to protect the state from the enemies within, who knows? What used to be blind patriotism when times were good is manifesting itself in disillusion in many. State of economy is always a catalyst for such events, with OWS movement spreading, with spring just around the corner; with no end in sight to the financial crises you might yet see that cult of personality in your own lifetime on your own streets. History proved it time and time again, it happen under monarchy, under dictatorial rule, under communism, what makes you so sure that pure capitalism or democracy is immune to it? The ambition of elites are not to be underestimated under any system but neither is the power of a hungry peasent.
This is why so many around the world want to be here.
The skeptic in me thinks that the reason for that is also a misconception, the news of economic hardship simply hasn’t reached them yet, they simply refuse to believe it or they have it even worse than you. The myth of great American dream persists in those on the outside; those on the inside are starting to have doubts as it can be observed in OWS movement, but for how long? Smoke and mirrors dear lady, smoke and mirrors. With your eternal optimism and my skepticism the truth must lie somewhere in the middle than.
