One point that is given considerable emphasis in the passage is that ----.

China's population is ageing and India's schools
are deteriorating. Economies in the developing
world are growing at nearly three times the rate of
those in the developed world; but perhaps they
won't be able to sustain this rate of growth. Maybe
it will take a little longer than thirty-five years to fulfil
Goldman Sachs's prediction that the world's ten
biggest economies will one day include Brazil,
Russia, Mexico, India and China. But these are
arguments about when, not whether, change will
happen. And growth rates could increase still
further: even the most optimistic predictions
underestimated Asia's ability to recover from the
financial crisis of 1997.
