On the other hand, it should be clear that having a stable wealth distribution over time is something desirable. So some regulation that stabilizes the wealth distribution and counteracts the forces that cause increasing inequality is simply necessary and common sense. The only question is what a desirable level of inequality is, and when you look at it that way, pretty much everybody (across the political spectrum) wants a more equal distribution than what we have today in almost all countries.
But how do you do that fairly? In the US at least, the richest people have the most wealth, but they also pay a lot more taxes. Not necessarily as a percent of income, but they pay a greater percent of the taxes than the percent of the wealth they hold. How would you propose making the distribution more equal?
Risking sounding like a broken record, our distribution of quality education is far more disturbing than our distribution of wealth. Near 15% of americans haven't graduated from high school. Near 50% of americans never graduated from college (2 year or 4 year). Only 29% have bachelors degrees or higher. 7% have masters degrees, and 2% have doctoral degrees. When viewed with that in mind the wealth distribution isn't nearly as negative.

The wealth doesn't have to be redistributed directly though, sending more tax money into public schools or for state scholarships for higher education will enable poor people to get a better education and thus increase their chances of breaking out of poverty through their own work, some inequality is necessary to keep people motivated. (Hard work has to pay off or people in general will simply try to do as little as possible).
As for the US the best way forward is probably to shift spending away from the military and towards more useful things (in 2010 US military spending was almost 20% of the total federal budget), the US is miles ahead of its potential enemies in terms of firepower and also has quite many reasonably strong allies, the risk that any country decides to attack the US is pretty much non existant. (Terrorists are a bigger threat but fighting those using a conventional army isn't very effective)
