Fair enough, perhaps people do want the rich to get more powerful in exchange for bread and circuses. But then what we're doing already is fine?
I think it's more complex than that. Voters have priorities, and those priorities are on a number of subjects. Subjects that are sometimes incompatible. Voters also have imperfect information, and are subject to being mislead. Voters also tend to take the word of 'our people' and discount the word of 'those people'. Then you have the party primaries, which are dominated by big money and big ideology voters. Then there are complex subjects where the soundbite works because the real explanation isn't so easily delivered. Then there are gerrymandered districts, which makes most people's votes not really count at all, and voter suppression efforts to block people from even having a chance to vote. And on top of all of that, there is a real large scale effort to demonize opponents in politics.
What this leaves is voters have to put in a real effort to know what a given candidate will do, and how what that candidate will do will affect them. These and other factors often lead to voters who don't really know where their best interest tells them to vote, or where they have issues that are just so much more important to them in one regard, and so they ignore the other factors.
So you have the 'values voters', the 'I vote pro life' voters, their first priority is not economic issues. And they tend to see their political opponents as bad, and untrustworthy, people, and so reject everything that they say. There is a very big overlap between these people and the 'salt of the earth' types you were describing above. These people are not voting on the debt, they are voting on other issues. But they are
voting for the debt! So these people may be against the debt, but they are voting for the debt. And they vote for the debt, in part because they don't have the information to make a more informed choice, in part because the system is rigged against their making an informed choice. And in part because, when push comes to shove, other issues simply matter more to them.
And that's what brings us all to the irony of the Tea Party and people who call themselves fiscal conservatives being the most pro-debt faction in American politics. Really the only faction in American political history who have ever tried to get the debt as high as possible as a tool to accomplish their other objectives.
