rich man, poor man

Jeg har den her tekst, og jeg forstår virkelig ikke meget af den.. er der nogen der kan hjælpe mig med af oversætte den?
One school, which blames globalisation, argues that the rocketing profits and sluggish middling wages of the past few years are the long-lasting results of trade, as all those new developing-country workers enter the labour market. This school says that technology helps workers by increasing their productivity and eventually their wages. The opposing school retorts that technology does not increase wages immediately, and some sorts of information technology seem to boost the returns to capital instead (think of how much more a dollar's worth of computing power can do these days). And it questions whether Western incomes will remain flat: recent wage rises in America and pay claims in Europe and Japan may start to reverse the balance back away from capital.

Skal nemlig svar på det her: what do they different schools mean?
tak, knus mig
