New Keynesian Economics

The global financial crisis has clearly illustrated that there is a serious vacuum of ideas on what to do next as a civilization. Majority of the public senses (on various levels) that key leaderships of many Western states do not offer much more beyond printing more money, socially brutal austerity, etc. Playing for time and looting are not solid ideas and everybody knows it. This inevitably opens up society to ideas from below which will eventually result in part of the elite siding with these ideas to co-opt them and ride them to power.
In United States, we saw the libertarian critique meme and the reactionary "going back to FDR policies" meme rapidly become dominant online over the last 2 years. Collapsist and neofeudalism memes are also about to become dominant. Collapsism in particular forces future oriented thought. The non-Internet world is quickly following behind since it took researchers a year or so to educate themselves about the fraud that caused the crisis, to put their books out, and then another few months for people to read the books. Various socially visible pundits can now defer to books as authoritative sources in speaking up. The market for new type of demagogy (talk radio being the old type) is nowhere near to being saturated.
This awakening resembles a sort of a popular front in the making since people from diverse ideological backgrounds are creating a consensus of what they are against (federal reserve corruption, military eating most resources, financial oligarchy and its personal lawyer/butler [US congress]). A marriage of convenience of this sort is usually created when all other options are exhausted and it will split into petty infighting once the current regime is changed.
All the accelerating muck racking and massive corruption exposures going on currently will begin to create a dissident critical mass in the near future. This is due to the gently exponential curve that is word of mouth communication and most importantly due to some elites sensing that popular sentiment now allows certain things to be safely discussed on a national level. Like in a jury herd dynamic, a minority of consistent and tireless individuals can swing the entire group whether at elite level, the level of a bar or church, or national level. The vacuum of workable ideas in leadership allows such informational waves to spread and take hold rapidly. It may have taken Christianity 300 years to become a dominant meme but with present communication technology, informational "viruses" can do the trick in just years.
