I am concerned about the drop in the value of the dollar, but it was actually too high for quite a long time, and had room to drop. It will help domestic industry become more competitive and after awhile, increase employment and exports, thing we really need help with.
That statement assumes that increased employment and exports is what the investor class wants. All available evidence says it isn't. What is there to export when we don't manufacture anything? Heck, about the only thing we're exporting today is our entire manaufacturing infrastructure as entire factories are disassembled and shipped over to China. How can employment be increased when there isn't anything for workers to do? We can't all schlep grease at McD's or stock shelves at Wally World.
In short, the investor class and the CEOs make their livings off short term increases in stock value. It doesn't matter how that's accomplished and if your company is incorporated in Belize it doesn't really matter what currency you trade in. The investor class has no incentive to build domestic industry, while at the same time Japan, Europe and every other country in the world does have incentive to make sure the US dollar doesn't go under since they own so much of the United States. For the US dollar to tank it would have grave economic implications for them.
Of course, the investor class doesn't care about this either. After all, they are only interested in short term gains so what do they care if the world economy goes to hell in a handbasket (with them throwing the basket into the hellmouth)? They will have made their nut and after the world economy has tanked they will have the power too -- just in time for a return to good old fedalism (with better marketing of course).
