Text 4 Economic theory suggests that regional inequalities should diminish as poorer places attract investment and grow faster than richer ones.The 20th century bore that theory out:income gaps narrowed across American states.No longer.Affluent places are now pulling away from poorer ones.This geographlcal divergence has dramatic consequences.Opportunities are limited for those stuck in the wrong place,and the wider economy suffers.If all its citizens had lived in places of high productivity over the past 50 years,America's economy could have grown twice as fast as it did.Divergence is the result of big forces.In the modern economy scale is increasingly important.The social network that everyone else is on is most attractive to new users;the stock cxchange with the deepest pool of investors is best for raising capital.These returns to scale create fewer,superstar firms clustered in fewer,superstar places.Everywhere else is left behind.Even as rcgional disparities widen,people are becoming less mobile.Demographic shifts help explain this.But the bigger culprit is poor policies.Soaring housing costs in prosperous cities kcep newcomers out.In America the spread of state-specific occupational licensrng and governmeni benefits punishes those who move.The pension of a teacher who stays in the same state could be twice as big as that of a teacher who moves mid-career.Perversely,policies to help the poor unintentionally exacerbate the plight of left-behind places.Unemployment and health benefits enable the least employable people ro survive in struggling places when once they would have had no choice but to move.Welfare makes capitalism Iess brutal for individuals,but it perpetuates the problems where they live.What to do?One answer is to help people move.Thriving places could do more to build the housing and infrastructure to accommodate newcomers.Accelerating the mutual recognition of credentials across state borders would help people move to where they can be most productive.But greater mobility also has a perverse side-effect.By draining poor places of talented workers,it exacerbates their troubles.The local tax-base erodes as productive workers leave,even as welfare and pension obligations mount.To avoid these outcomes,politicians have long tried to bolster left-behind places with subsidies.But such"regional policies"have a patchy record,at best.Better for politicians to focus on speeding up the diffusion of technology and business practices from high-performing places.A beefed-up competition policy could reduce industrial concentration,which saps the economy of dynamism while focusing the gains from growth in fewer firms and places.Fostering clusters by encouraging the creation of private investment funds targeted on particular regions might help.Perhaps most of all,politicians need a different mindset.For progressives,alleviating poverty has demanded welfare;for libertarians,freeing up the economy.Both have focused on people.But the complex interaction of demography,welfare and globalisation means that is insufficient.Easing the anger of the left-behincl means realising that places matter,too.
The geographical inequality in America______.

A.is a normal economic phenomenon
B.results from investment imbalance
C.has been largely eliminated
D.slows the overall economy down

The last time she was recruiting for her export-sales team,Sarah Grain hired a Lithuanian who speaks Russian,Polish and German.Her two previous hires for Eriez Magnetics,which makes in-dustrial equipment in South Wales,were an Italian who also speaks French,and a Venezuelan who speaks Spanish and Portuguese.All of them speak fluent English."There were no British applicants who had the requisite language skills,"she says.Ms Grain's conclusion is not unusual for a British company.In 2012 a European Commission survey tested the foreign-language proficiency of 54,000 students aged 14 and 15,in 14 nations.Sweden came top,with 82qo of pupils reaching an"independent"or"advanced independent"standard.The average for all 14 states was 42%.England came bottom,with just 9%.Part of the explanation is that many people's second language is English,while many Britons continue to believe that,as native speakers,they do not need to bother with foreign languages.They may be right-in tenns of commurucation.But it means that,not only are they missing out on much cultural interaction,they may also be harming their own job prospects.they have not been helped by the educational policies of successive govemments.In 2004 Tony Blair's hbour govemment abolished the requirement to learn a language after the age of 14,causing the numbers taking a language CCSE exam at 16 to fall by half in state schools over the next seven years.Concerned about this rapid decline,the coalition govemment brought in a new performance indicator called the English Baccalaureate,or EBacc,in 2011.A modern language was one of its five core disciplines.Language teachers-an embattled breed-rejoiced.The number of students ente-ring a GCSE language exam in 2013,the first year the changes took effect,rose by 20%.Now,however,those gains could be lost,as the govemment has seemingly loosened the re-quirement.From 2016,under a new initiative called Progress 8,it has extended the number of core subjects to eight,appearing to make learning a language voluntary.This has pleased some teachers,who felt the EBacc was too narrow,but linguists are shocking.The decline of languages at GCSE has inevitably had an effect higher up the academic food chain.Though the number of those studying languages to A Level will increase thanks to the GCSE cohort of 2013-2014,it is likely to fall back again.French and German are half as popular as they were 20 years ago.The number of universities offering language degrees has fallen,too:by 50%for Cerman and 40%for French since 1998.The number offering Spanish has also fallen.Degrees in other languages,such as Chinese and Arabic,are becoming more popular,but they are still rare.The economy and the labour market bear the consequences.In 2012 the British Chambers of Commerce found,in a survey of 8,000 BriLish companies,that 96%had no foreign-language speakers.First-lime exporters cited language as a barrier to entering intemational markets.Though Britain makes up 12%of the population of the EU,less than 5qo of EU civil servants in Brussels are British.Not enough Bricons can fulfil the language requirement of being able to work in French or Cerman.And even if monoglot Brits can get jobs at multinationals,claims Richard Hardie,non-executive chairman of the British arm of UBS,a bank,"the chances of getting to the top if you only have English are much lower than before".
