The possible causes of the world stock-exchange crash
 

Not long ago there was a owner of a big food-production-firm, who went to the stock market in Vienna. He sold at the stockexchange many thousand shares of his firm for about 100 € each to the public. Then this mighty business man pushed down the couse of his shares to 50% by the help of the former Austrian minister of finance. The shareholders got therfore very nervous and nearly all of them sold their shares back to the food-production-firm-owner to the lower prize of 50 €. Therefore this businessman had an astronomical profit by this stock-exchange manipulations. Then some of the persons, who had sold back their shares, feeled themselves betrayed and went to court for accusation. But the judges of the lawcourt did not found an evidence of guilt .

The horror.

If you think that's bad- wait until the OPEC, China, and other nations dumps the dollar. Ever seen 20 dollar per gallon gas? Movement of freight would stop immediately- as the cost effectiveness of moving goods via rail or road would be many times the profit of moving them. Distribution centers typically hold enough goods for roughly a week (assuming they can deliver). Grocery stores for a day or so at the maximum.

If you ever hear that freight stops moving, you can expect food riots within a few days. I'm not sure how similar it would be in Japan, but most westernized countries I would assume it would be this way. Worse- it would be a chain reaction. When this happened to Iceland, world stock markets suffered. If this happened with an economy the size of the US- world economic implosion. Google Gerald Celente at the Trends Research Institute if you have the mind for it. His predictions have been right on so far.

sorta not
 

Gerald Celente does nothing but rant about current day issues. When prompted for his solution he says that we need Cold Fusion, Zero-Point Energy, or something equivalent to the Internet (which he failed to predict).

He left the solution to the Engineers and the Scientists as he claims that his mind could not wrap around such things. The first two are works of science fiction and things that are touted as foolish attempts to obtain the Philosopher Stone in academia but spun up into fairy tales to be told as potential technology to the general public through Popular Science or the likes.
Bottomline: Complainers complain while scientists and engineers work for a solution.
OPEC and China replacing the dollar arguement - is older than the internet.

There is no such fantasy as the 'world stock exchange.' get into line with the rest of the wingnut crowd.

sounds about the default answer for your neck of the woods. Thank you for playing.
