I think from whatever perspective you approach US Government, you'll find frustration. Our system of government isn't perfect, and was never created to be that way, only to aspire to be better.
When people go on and on about the US being the end-all, be-all of the world, that gets me frustrated; not in their blindness to the way the world works, but to the increasing amount of lazy stock many Americans place in a government that has and will lie to them; and ignores many social needs in favor of corporate profit. That's my frustration.
As far as comfortability goes, I'm fairly happy. I'm not ducking bombs or checkpoints or the clashes of rival warlords (
unless you consider consumer goods manufacturers to be warring factions, then yes).
The cost of a human life in the US is so high that we squabble over whether or not a newly-inseminated embryo is considered "alive", where in other countries,
starving children are treated as vermin to be exterminated. I'm comfortable with that, and the political BS that comes along with the squabble here in the US.
My basic needs are met. Outside of taxation, the government has no control over my right to pursue my life needs. My family is not in some concentration/labor camp
like in other countries. That's pretty cool, too.
I'm also ecstatic that I can complain all I want about the government, and I can also get other people to agree with me, and not have government agents banging on my door to "ask me questions."
In general, I'm not truly happy with the US government or what they are doing. Nor am I truly dissatisfied. People who truly believe they are completely happy/dissatisfied with the government are sheep. Sorry.
Our government was meant to be a perpetual work in progress. And that means having an opinion and remaining actively informed of the world around, and not giving in to propaganda or defeatist mentality when it comes to making a change.
