A、Mess on the Ladder of Success A、ThroughoutAmerican history there has almost always been at least one central economic narrative that gave the ambitious or unsatisfied reason to pack up and seek their fortune elsewhere. For the first 300 or so years ofEuropean settlement, the story was about moving outward: getting immigrants to the continent and then to the frontier to clear the prairies(大草原), drain the wetlands and build new cities. B、By the end of the 19th century, as the frontier vanished, the US had a mild panic attack. What would this energetic, enterprising country be without new lands to conquer Some people, such as Teddy Roosevelt, decided to keep on conqueringCuba, the Philippines, et

C、), but eventually, in industrialization, the US found a new narrative of economic mobility at home. From the 1890s to the 1960s, people moved from farm to city, first in the North and then in the South. In fact, by the 1950s, there was enough prosperity and white-collar work that many began to move to the suburbs.As the population aged, there was also a shift from the cold RustBelt to the comforts of the SunBelt. We think of this as an old person’s migration, but it created many jobs for the young in construction and health care, not to mention tourism, retail and restaurants. C、For the last 20 years from the end of the cold war through two burst bubbles in a single decade-the US has been casting about for its next economic narrative.And now it is experiencing another period of panic, which is bad news for much of the workforce but particularly for its youngest members. D、The US has always been a remarkably mobile country, but new data from theCensusBureau indicate that mobility has reached its lowest level in recorded history. Sure, some people are stuck in homes valued at less than their mortgages(抵押贷款), but many young people-who don’t own homes and don’t yet have families-are staying put, too. This suggests, among other things, that people aren’t packing up for new economic opportunities the way they used to. Rather than dividing the country into the 1 percenters versus(与......相对) everyone else, the split in our economy is really between two other classes: the mobile and immobile. E、Part of the problem is that the country’s largest industries are in decline. In the past, it was perfectly clear where young people should go for workChicago in the 1870s,Detroit in the 1910s, Houston in the 1970s) and, more or less, what they’d be doing when they got there (killing cattle, building cars, selling oil).And these industries were large enough to offer jobs to each class of worker, from unskilled laborer to manager or engineer. Today, the few bright spots in our economy are relatively small (though some promise future growth) and decentralizeD、There are great jobs in Silicon Valley, in the biotech research capitals ofBoston and Raleigh-Durham and in advanced manufacturing plants along the southern z-85 corridor. These companies recruit all over the country and the globe for workers with specific abilities. (You don’t need to be the next Mark Zuckerberg, founder of Facebook. to get a job in one of the microhubs(微中心), by the way.But you will almost certainly need at least a

B、

A、in computer science or a year or two at a technical school.) This newer, select job market is national, and it offers members of the mobile class competitive salaries and higher bargaining power.F) Many members of the immobile class, on the other hand, live in theAmerica of the gloomy headlines. If you have no specialized skills, there’s little reason to uproot to another state and be the last in line for a low-paying job at a new auto plant or a green-energy startup. The surprise in the census(普查) data, however, is that the immobile workforce is not limited to unskilled workers. In fact, many have a college degree.G) Until now, a

B、

A、in any subject was a near-guarantee of at least middle-class wages.But
