I am missing something here...... If AMERICANS cannot afford to buy US products and buy from China.... who is buying the US products?

From what I see, other countires only buy what they cannot make themselves... China may buy steel or wood... and will continue to buy... but they are not going to buy made in USA cheap transistors or kiddies toys....

The USA does not NEED Chinese Ghetto blasters and kids toys, they buy them because they are cheap... china however NEEDS raw products from other countries?

I am no economist, so Imay be a bit ahead of myself here...
Ok im not an expert on what the US exports and imports as im from Belgium so i cant really think of any examples to support my claim, anyways lets start.

consumers in a somewhat capitalist country dont only choose which products they are gonna buy acording to what they can afford what they cant, competition and thus the fact they can choose between several somewhat similar products.
So US consumers buy chinese kiddy toys because they have the best quality/price ratio.
On the other hand US producers might be able to produce and export another product at a better price/quality ratio then chinese producers and thus will be exporting to China.
This will then lead to specialisation of certain countries in certain sectors and will eventually lead to an increased production, employment and more economical activity (its called the law of ricardo i think).

Also you should not group all the products a country produces, there is no single market of "all products", similar products from all over the world are grouped in markets that have vastly different dynamics according to production proccesses and competition from other markets.
Also of note is that capitalistic systems work along a system of offer and demand, so if there is no demand for a product then there will be no offer.
And off course the fact that "countries" in general dont import or export, private citizens do it and they can only be "coached" by governements by using taxes and subsidies, but these private citizens still work for the acquirement of profit.

Also of note is that protectionist measures to strengthen your domestic economy is not something that only involves China, it involves every country that the US imports to or exports from, now a change in the export/import dynamics could not be that bad in the case of one country, but it might be devestating if done between other countries, say Europe and US.

So that was my little rant about international trade, i am also not an economist but in middle school i specialized in economics and this was practicly what i understood from that course, so if somebody who contrary to me actually knows what he is talking about, and sees im wrong please correct me.
