*** this is slightly hyper, but go by the sentiment, not the tone ***
check the markets. if you are invested in stocks, you are already impacted.
however, what you are seeing is a starting point (or is it already halfway) of the decline of the american empire and the rise of a chinese one. maybe it will not go that far, but you have to see the difference between a) on one side the chinese who are building capacity, working hard i guess, supplying such cheap goods, and their leaders in single-minded pursuit of growth b) on the other hand americans who are living on debt, mired in politics and hence unable to decide anything, controlled by big business to their own detriment ... the direct consequences of this will not be known for years, maybe decades.
but i was reading a report that china and japan hold 1.2 and 0.9 trillion USD worth of treasury notes, which is what essentially we borrowed from them. there was already a talk of china diversifying from USA, however, paul krugman calls it mutual destruction since china dumping even 10% of their holdings will bring down the dollar so much that they will lose the remaining 90%. but nothing stops them from making a 1-2% change every year and diversifying into other currencies. they will also start making yuan more of an international currency so they need less us dollars going forward. net result ... value of dollar falls (devaluation) and you have to pay more to import which means most of your clothes become expensive. on the positive side you can export more since the price is not so much in local currencies. however, what does US export nowadays (ignore canada and mexico which are neighboring countries) except technology and financial leverage models? and technology is moving to india and china.
so in 10 years (unless things change), you can not import as much as you do not have money, and you can not export as much as you do not have industry. while this creates opportunities for entrepreneurs to create some new business models, the big business will not let that happen. welcome to the league of "developing countries", in a few decades.
nothing is irreversible, but s&p is right, the gridlock is so bad that even after the next election and unless someone gets 90% of the vote, things ain't going to change.
