Some cat, ani and a settling tank does for most of it. Wrote a program to monitor and control feed rates for that type of equipment once upon a time. Upset NALCO chemical no end, since it actually cut costs.
To recognize suppression of speech or anything from left and right, you have to be aware they use utterly different methods. The left usually goes for a bottom up approach, trying to instill a distaste for certain items or words, and tries to spread that into a mass movement. The right goes for a top down approach, usually not visible to the average joe, where they move (promote) influential individuals out of visible positions to less visible positions, investigative reporters get assigned to covering the Hollywood beat, etc. So the left is fairly obvious in their tactics to suppress undesirable speech, the right is generally sneakier about it, save that some just can't keep from bragging about their moves. This is and has been the common pattern in the US at least since the Civil War and probably before. Attempts to control the public discourse generally peak shortly before the runup to the crisis begins. The 1998 communications act was certainly a capper in these movements (if you recall, the PC push on college campuses was reaching a peak at that time as well) and the final runup to the housing crash started shortly afterwards.
Vince, if we assume the EURO will survive, then perhaps printing physical EUROS would be a good thing overall. At least there would be SOME money in existence after the electrons go to zero. But I seriously doubt this is happening on any scale large enough to be noticed. This is, and has been since 1600, the age of debt and will continue to be so into the future for some time yet.
The great push for the future will simply be this, an end to fear. Fear of losing a job, fear of being homeless, fear of starving, fear of war or oppression or being damaged by action of government or corporation or crime. Any politician who wants to be elected now would be wise to speak of ending fear. This is the time and the season for such matters to come round once again.
Just MHO, but I think we'll see markets moving downwards generally for some time now. There will doubtless be widely ballyhooed upticks, but the trend overall is going to be down.
In re that economics review article, it's very much worthy of note that listening to people griping about government for a while reveals an interesting fact, they are often complaining about things done by corporations, not government per se. There is a great dichtomy in American thought that separates "business" as good and "government" as bad, so many things forced upon us by corporations are derided as government, even when it's not. As many such divisions do, this one will one day reverse itself and probably quite suddenly, so that business will be "bad" and government will be "good". Such simple divisions are rarely accurate in even the broadest terms, but are very attractive to the public overall.
