12、ephen Koziatek feels almost as though he has to justify his efforts to give his students a better future。Mr。 Koziatek is part of something pioneering。 He is a teacher at a New Hampshire high school where learning is not something of books and tests and mechanical memorization， but practical。 When di

13、d it become accepted wisdom that students should be able to name the 13th president of the United States but be utterly overwhelmed by a broken bike chain？As Koziatek knows， there is learning in just about everything。 Nothing is necessarily gained by forcing students to learn geometry at a graffitie

14、d desk stuck with generations of discarded chewing gum。 They can also learn geometry by assembling a bicycle。But hes also found a kind of insidious prejudice。 Working with your hands is seen as almost a mark of inferiority。 Schools in the family of vocational education “have that stereotype。that its

15、 for kids who cant make it academically，”he says。On one hand， that viewpoint is a logical product of Americas evolution。 Manufacturing is not the economic engine that it once was。 The job security that the US economy once offered to high school graduates has largely evaporated。 More education is the

16、 new principle。 We want more for our kids， and rightfully so。But the headlong push into bachelors degrees for all and the subtle devaluing of anything less misses an important point： Thats not the only thing the American economy need。 Yes， a bachelors degree opens more doors。 But even now， 54 percen

17、t of the jobs in the country are middle-skill jobs， such as construction and high-skill manufacturing。 But only 44 percent of workers are adequately trained。In other words， at a time when the working class has turned the country on its political head， frustrated that the opportunity that once define

18、d America is vanishing， one obvious solution is staring us in the face。 There is a gap in working-class jobs， but the workers who need those jobs most arent equipped to do them。 Koziateks Manchester school of Technology High School is trying to fill that gap。Koziateks school is a wake-up call。 When

23、ing up momentum around the world： They now account for more than half of new power sources going on line。Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources。 But increasingly the story is about the plummeting prices of renewables， especially wi

24、nd and solar。 The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years。In many parts of the world renewable energy is already a principal energy source。 In Scotland， for example， wind turbines provide enough electricity to power 9

25、5 percent of homes。 While the rest of the world takes the lead， notably China and Europe， the United States is also seeing a remarkable shift。 In March， for the first time， wind and solar power accounted for more than 10 percent of the power generated in the US， reported the US Energy Information Ad

26、ministration。President Trump has underlined fossil fuelsespecially coalas the path to economic growth。 In a recent speech in Iowa， he dismissed wind power as an unreliable energy source。 But that message did not play well with many in Iowa， where wind turbines dot the fields and provide 36 percent o

34、just announced the purchase of the upmarket grocery chain Whole Foods for $l3.5bn，but two years ago Facebook paid even more than that to acquire the WhatsApp messaging service， which doesnt have any physical product at all。 What WhatsApp offered Facebook was an intricate and finely detailed web of i

35、ts users friendships and social lives。Facebook promised the European commission then that it would not link phone numbers to Facebook identities， but it broke the promise almost as soon as the deal went through。 Even without knowing what was in the messages， the knowledge of who sent them and to who

36、m was enormously revealing and still could be。 What political journalist， what party whip， would not want to know the makeup of the WhatsApp groups in which Therea Mays enemies are currently plotting？ It may be that the value of Whole Foods to Amazon is not so much the 460 shops it owns， but the rec

37、ords of which customers have purchased what。Competition law appears to be the only way to address these imbalances of power。 But it is clumsy。 For one thing， it is very slow compared to the pace of Change within the digital economy。 By the time a problem has been addressed and remedied it may have v

39、vices are not their customers。 That would be the people who buy advertising from them-and Facebook and Google， the two virtual giants， dominate digital advertising to the disadvantage of all other media and entertainment companies。The product theyre selling is data， and we， the users， convert our li
