Is Wall Street both legalized gambling and a group of the world's largest International companies?

So if we let "the market" dictate all our policies isn't that giving yet more influence for International companies to buy low, pollute high, and make as much money as they can from the USA because we are but a group of buyers in the world economy. Add to that that Wall Street is also a Casino, and it's hard to understand those that trust that machine to fix the sagging USA economy. Let's face it they are basically doing that now and the Wall Street Casino is doing great and the USA economy is in shambles. Do you think rilling more or polluting more is the magic bullet? So who is this "Market" you expect to fix the problems in the USA vs. government, how does that really work other than as a slogan, that really no one thinks through? How can International corporations that are Wall Street, and legalized gambling that is Wall Street get our economy on track better than say, firing all the jokers in DC who are already reporting to them and reworking the goverment to be less corrupt and less tied to Wall Street profits and the casino.
