Disruption may bc the buzzword in boardrooms, but the most striking feature of business today is not the overturning of the established order. It is the stabilisation of a group of superstar companies at the heart of the global economy. Some are emerging-market champions, like Samsung, which have seized the opportunities provided by globalisation. The elite of the elite are high-tech wizards-Google, Apple, Facebook and the rest-that have conjured up corporate empires from bits and bytes.
The superstars are admirable in many ways. They churn out products that improve consumers' lives, from smarter smartphones to sharper televisions. They provide Americans and Europeans with an estimated $280 billion-worth of "free" services-such as search or directions-a year. But they have two big faults. They are squashing competition, and they are using the darker arts of management to stay ahead. Neither is easy to solve. But failing to do so risks a backlash which will be bad for everyone.
Bulking up is a global trend. The annual number of mergers and acquisitions is more than twice what it was in the 1990s. But concentration is at its most worrying in America. The share of GDP generated by America's 100 biggest companies rose from about 33% in 1994 t0 46% in 2013. In the home of the entrepreneur, the number of startups js lower than it has been at any time since the 1970s. More firms are dying than being bom. Founders dream of selling their firms to one of the giants rather than of building their own titans.
The weight of the superstars also reflects their excellence at less productive activities. About 30% of global foreign direct investment (FDl) flows through tax havens, big companies routinely use "transfer pricing" to pretend that profits generated in one part of the world are in fact made in another. None of this helps the image of big business. Paying tax seems to be unavoidable for individuals but optional for firms. Rules are unbending for citizens, and up for negotiation when it comes to companies. Nor do profits translate into jobs as once they did. In 1990 the top three carmakers in Detroit had a market capitalisation of $36 billion and l.2 million employees. In 2014 the top three firms in Silicon Valley, with a market capitalisation ofover $l trillion, had only 137,000 employees.
So, by all means celebrate the astonishing achievements of today's superstar companies. But also watch them. The world needs a healthy dose of competition to keep today's giants on their toes and to give those in their shadow a chance to grow.
31. According to Paragraph l, today's business world is
  • A. disrupted by innovative enterprises
  • B. out of order by traditional companies
  • C. dominated by superstar companies
  • D. distracted by emerging market

Smartphones have by now been implicated in so many crummy outcomes-car fatalities, sleep disturbances, empathy loss, relationship problems, failure to notice a clown on a unicycle-that it almost seems easier to list the things they don't mess up than the things they do. Our society may be reaching peak criticism of digital devices.
Even so. emerging research suggests that a kev Droblem remains underaDDreciated. It involves kids' development, but it's probably not what you think. More than screen-obsessed young children, we should be concerned about tuned-out parents.
Yes, parents now have more face time with their children than did almost any parents in history. Despite a dramatic increase in the percentage of women in the workforce, mothers today astoundingly spend morc time caring for their children than mothers did in the 1960s. But the engagement between parent and child is increasingly Iow-quality, even ersatz. Parents are constantly present in their children's lives physically, but they are less emotionally attuned. To be clear, I'm not unsympathetic to parents in this predicament. My own adult children like to joke that they wouldn't have survived infancy ifl'd had a smartphone in my clutches 25 years ago.
To argue that parents' use of screens is an underappreciated problem isn't to discount the direct risks screens pose to children: Substantial evidence suggests that many types of screen time (especially those involving fast-paced or violent imagery) are damaging to young brains. Today's preschoolers spend more than four hours a day facing a screen. And, since 1970, the average age of onset of "regular" screen use has gone from 4 years to just four months.
Some of the newer interactive games kids play on phones or tablets may be more benign than watching TV or YouTube, in that they better mimic children's natural play behaviors. And, of course, many well-functioning adults survived a mind-numbing childhood spent watching a lot of cognitive garbage. (My mother-unusually for her time-prohibited Speed Racer and Gilligan's Island on the grounds of insipidness. That I somehow managed to watch every single episode of each show scores of times has never been explained.) Still, no one really disputes the tremendous opportunity costs to young children who are plugged in to a screen: Time spent on devices is time not spent actively exploring the world and relating to other human beings.
21. We can learn from the first two paragraphs that smartphones .
  • A. hardly have any advantages
  • B. bring numerous bad effects
  • C. bear the most severed criticism
  • D. have little effect on parents
