Is the American economy heading into 'dire straights'?

 Investments are on the down track. I wonder how long they will go down. According to the video there is correction and there is downturn in the market. The question is how long and how severe the downturn? I would think that some of the investments we have put into our infrastructure and economy may help reduce some of that downswing. However, that may or may not be true depending on lots of other factors.
