>Remember the oil crisis 1974? The german (west) economists were predicting large fall of retail, seeing in advance how Germans will drop the luxury, travel less, even that the sales of beer will fall. None of which have happened to any serious extent, because the practical people ditched the church tax first and found that that was enough of a saving (hey, I said "a saving", not "a savings" - if you hear I was assassinated, this is why). Why didn't any of economists predict that, if it was so obvious to the statistical majority of people?

No I don't remember that. Problem had no influence in the GDR.

Because the statistical majority of people didn't ditch those tax. In bavaria they believe one can not be buried without it (no joke. Oldest daughter lives there and get this question as the others figured out she is not in this gang. Six months ago)

The failure / system discussion is depending on the model you use. If you like the model straight, you add up anything else into failure. :D (So the professor told us. I've a diploma in this.)
