Passage OneQuestions 46 to 50 are based on the following passage.AAny young Britons believe that the housing market is stacked against them. And who can blame them? In the past two decades, house prices have doubled in real terms, because of hours more planning restrictions, which have limited the supply of homes, and low interest rates, which have pushed up the demand for them.There's Alan, the prime minister, has described the scarcity of housing as "the biggest domestic policy challenge of our generation". But the reality is that it challenges some generations more than others. Elderly folk, who bought their houses before the boom, own a huge slice of overall housing wealth relative to their share of the population. It is a different story for youngsters. A 27-year-old living today is half as likely to be a home-owner as one living 15 years ago.Yet some economists spot a silver lining for millennials. The thinking goes that, within a decade or two, baby-boomers — the large generation born between roughly the early 1980s and early 1960s — will begin to sell up, as they first start to downsize, then move into elderly people's accommodation and, eventually, to the great old folks' home in the sky.However, so far the British boomers are in no rush to scale down. In contrast to America, Britain does not have much of a downsizing culture. By one calculation just 40% of Britons who owned their homes at age 50 will move house before they die. A paper published in 2011 provides convincing evidence that geography and climate play a big role. In America oldsters can move to sunny climes like Florida Britain is a bit short on such places-Cornwall, lovely as it is, is not known as the "Sunshine County" —so most homeowners don't move.Besides, the impact of the great baby-boomer sell-off will have an unequa effect on different groups of youngsters. The boomers will leave record amounts of wealth to their descendants. However, nearly half of non-home owning millennials have no parenta property wealth at all, according to a research. The other half will be able to use their inheritance to gain greater purchase in the housing market, for themselves or their own heirs and heritresses. A class of wealthy oldsters is moving on, only to be replaced by a class of wealthy inheritors.46.
