[单项选择]Nationally, an ageing population is a problem. But locally it can be a boon. The over-50s control 80% of Britain"s wealth, and like to spend it on houses and high-street shopping. The young "generation rent", by contrast, is poor, distractible and liable to shop online.
People aged between 50 and 74 spend twice as much as the under-30s on cinema tickets. Between 2000 and 2010 restaurant spending by those aged 65-74 increased by 33%, while the under-30s spent 18% less. And while the young still struggle to find work, older people are retiring later. During the financial crisis full-time employment fell for every age group but the over-65s, and there has been a rash of older entrepreneurs. Pensioners also support the working population by volunteering: some 100 retirees in Christchurch help out as business mentors.
Even if they wanted to, most small towns and cities could not capture the cool kids. Mobile young professionals cluster, and greatly prefer to cluster in London. Even supposed meccas like Manchester are ageing: clubs in that city are becoming members-only. Towns that aim too young, like Bracknell and Chippenham, can find their high streets full of closed La Senzas (a lingerie chain) and struggling tattoo parlours.
Companies often lag behind local authorities in working this out. They are London-obsessed, and have been slow to appreciate the growing economic heft of the old—who are assumed, often wrongly, to stick with products they learned to love in their youth. But Caroyln Freeman of Revelation Marketing reckons Britain could be on the verge of a marketing surge directed at the grey pound, "similar to what we saw with the pink". The window will not remain open forever: soon the baby boomers will start to ail, and no one else alive today is likely to have such a rich retirement.
Meanwhile, with the over-50s holding the purse strings, the towns that draw them are likely to grow more and more pleasant. Decent restaurants and nice shops spring up in the favoured haunts of the old, just as they do in the trendy, revamped boroughs of London. Latimer House, a Christchurch furniture store full of retro clothing and 1940s music, would not look out of place in Hackney. Improved high streets then entice customers of all ages.
Indeed, gentrification and gerontification can look remarkably similar. Old folk and young hipsters are similarly fond of vinyl and typewriters, and wander about in outsized spectacles. Some people never lose their edge.The ageing population can be locally a boon in Britain in that ______.
A. old folks hold 80% of Britain"s wealth
B. older people spend more money on high-street shopping
C. older people tend to buy big houses than rent houses
D. the elderly like shopping online
