Okay then who buys the excess goods? You need a consumer. Is the American government going to buy all the excess and bankrupt itself? I can't see a good end to capitalism, even with keynesian economics. It can't last forever when everyone is able to compete.
'Buy'? What does that even mean? Just print the money.. or simply order them made at gunpoint and throw them into the sea if there are too many of them. Get creative.. don't be boxed in by the idea of 'money' or 'bankruptcy'.
The thing to remember about economics is there are real productive capacities out there being ordered by the State - the market is just a fiction created by the privatization of these resources. We allow a lot of little barons control over our resources, so they tend to destroy them, mismanage them, etc etc. There is no need to allow this.
