perception
There are a number of points here I think quite worthy of discussion: a 'disconnection' between both media and the political crowd with the general population; the 'apathy' in the general population; tougher economic times and causes/remedies for that; and who has been alerting the public to the tough economic realities of an aging boomer population.
So this is actually quite a substantial bit of stuff to deal with.
On the disconnection issue, I know of no better book which addresses this problem than Joan Didion's "Political Fictions". But it is a huge issue, and I can't do it any justice here, if anywhere.
Likewise, the 'apathy'. Clearly, is seems related to the disconnection issue. We do know, from so many different experiences, that the political structure and rather too many of the folks who populate it are often playing quite a different game than they state. We commonly think of them as deceitful and self-interested, and not as truthful, well-intentioned civic servants. No small task to analyse this or to turn it around.
Regarding the tougher economic times - causes and solutions - even among economists there is nothing like consensus (I'll add a link here to an incredibly good PBS series on economics which is available to watch and read transcripts of on-line

Your last issue is one that perhaps I can address. Your claim, unless I have it wrong, is that it is or has been mainly the conservative element which has raised the alert on the increasing cost of social programs and of security, and thus, the need to raise taxes.
I don't think I can agree. My recollection is that various voices, but mainly from the economics crowd, have been warning for some time (20 years) about the aging boomer population and the economic consequences associated. The largest downward revision of social programs in the last three or five decades occured under Clinton. Also, we ought to recall that the deficit was considerably reduced at that time. Further, we ought to recall that the deficit burgeoned most acutely under Reagan, and it looks like it is going to happen again under Bush.
