I've been seeing this a lot on both sides of the debate and now just capped off my Joe Scarborough and his band of minions. In discussing the Geithner "plan" that was outlined yesterday, the market is often used in place of an actual argument; "We were unimpressed by Geithner" chirps JS before citing the -380 DJIA as his evidence. Or bloggers that lambast the lack of detail in Geithner's speech, and then use the market plummet as an unquestionable display of their correctness.
However, many of these people are among those who argued "fuck Wall Street, who cares what they say, this is about real jobs, and nobody who works on Wall Street has a real job, so let's cap their pay at some random number, because they all live in Greenwich, and let's not take any more cues from them, because the eras of big bonuses or soaring profits for the investor class are over, so let's break the stranglehold that Wall Street lobbyists have on Congress." And if you are one of those who made an appeal of this sort, then please shut the fuck up about how the markets react.
