labour is just another copmmodity and so will move to where its cheaper...all other things being equal. Of course in not too long then the countries where we are exporting these jobs too, will in turn lose these jobs to countries less developed (and hence cheaper) than their own. Of course by then our concerns maybe different as they will be looking for mandarin speaking call centres and not english :-)
And of course we have benefitted from low inflation due to all the cheap imported goods we have received from china over the last 15 years or so...
