If spending is a measure of what matters, then the people of the developing world place a high value on brains. While private spending on education has not changed much in the rich world in the past ten years, in China and India it has more than doubled. Since brainpower is the primary generator of progress, this burst of enthusiasm for investing in private education is excellent news for the world. But not everybody is delighted. Because private education increases inequality, some governments are trying to stop its advance. That's wrong: they should welcome it, and spread its benefits more widely.
① Education used to be provided by religious institutions or entrepreneurs. But when governments, starting in Prussia in the 18th century, got into the business of nation-building, they realized they could use education to shape young minds. As state systems grew, private schooling was left to the elite and the pious(虔诚的). Now it is enjoying popularity again, for several reasons. Incomes are rising, especially among the better off, at the same time as birth rates are falling. In China the former one-child policy means that six people—two parents and four grandparents—can pour money into educating a single child.
② All over the developing world, people want more or better education than governments provide. Where cities are growing at unmanageable speed, the private education istaking up the slack.In India the private education now educates nearly half of all children, in Pakistan more than a third, and in both countries the state education is shrinking. Even where the state does pretty well, as in East Asia, richer people still want better schooling for their children than the masses get. Thus, Vietnam, which has an outstanding state-school system for a poor country, measured by its performance in the OECD's PISA test, also has the fastest-growing private education.
③ In most ways, this is an excellent thing, because the world is getting more and better schooling.
In rich countries, once the background and ability of the children who attend private schools are taken into account, their exams results are about the same as those in the state education. But in developing countries private schools are better—and much more efficient. A study of eight Indian states found that, in terms of learning outcomes per rupee, private schools were between 1.5 times and 29 times more cost-effective than state schools.
④ They tend to sort children by income, herding richer ones towards better schools that will enhance their already superior life chances. That is one reason why many governments are troubled by their rise.
Governments are right to worry about private education's contribution to inequality, but they are wrong to discourage its growth. Governments should instead focus on improving the public education by mimicking(模仿) the private education's virtues. Freedom from independent management is at the root of its superior performance and greater efficiency. Governments should therefore do their best to give school principals more freedom to innovate and to fire underperforming teachers.
To spread the benefit of private schools more widely, governments should work with them, paying for education through vouchers(代金券) which children can spend in private schools. And vouchers should be limited to students in non-selective schools that do not charge top-up fees; otherwise governments will find themselves helping the better off and increasing inequality.
The world faces plenty of problems. Governments should stop behaving as though private education were one of them. It will, rather, increase the chances of finding solutions.
