The whole financial structure of Wall Street seems to rise or fall on the mere fact that the Federal Reserve Bank raises or lowers the amount of interest. Any business that can't survive a one percent change must be skating on thin ice.
Why even the poor farmer took a raise of another ten percent just to get a loan from the bank, and nobody from the government paid any attention. But you let Wall Street have a nightmare and the whole country has to help to get them back into bed again.
