Earlier quoted context omitted.
I don't disagree at all. I just don't see how railing against the notion of inequality does anything to address this - the US collects enough in tax revenue to solve these problems already. What it needs is better policy. I should also mention that I live in Canada which, though flawed in many ways, seems to have struck a better balance.
Canada (and most of Europe, for that matter) don't bear the costs of their own defense. That helps a lot. You may be wondering who would want to attack Canada. Well, you have an awful lot of wheat and oil, and China has an awful lot of hungry people and factories.
Would China invade Canada if the world's defence budgets dropped precipitously? Probably not - it has far more to gain through trade than by attempted colonization.
In fact, last time I checked nobody in Canada or Western Europe was asked to vote on the US defense budget. I'd gladly vote to cut it in half and devote more to shoring up your healthcare system, but it's a sovereign issue and it's up to Americans to solve it for themselves.
