I dont know why loote gives good argument and completely spoils with one or two stupid resoning.Another slave of whilte is loote. You only have to know the GDP of china and USA . In last 25 years China GDP is over 8% where as USA is 3%.. Now china GDP is well over 13%. You can say mirosoft is USA and they are exploiting chinese. I dont know if US is exploiting china because with the current GDP rate china will overtake US economy by 2020. All knows sooner or later USA will succumb to terrorism because you cannot gain new enemies everyday and still survive. Terrorism will be main downfall of US economy. If you do a research in any technical field just go though either IEEE or IEE journals their you will find out how much chinese people have carried out research. I have been carrying out research myself and almost 50% of the journals i took had some chinese names in them.Thousands of them work for US (in your word exploitation) but dont forget chuck of them (may be millions of them) still reside in china. I have been studying with almost 40 chinese students and about 2/3 of them want to go back home because they are contracted by companies.
