AT the recent New York Times forum in Singapore, Eleonora Sharef, a co-founder of HireArt, was explaining what new skills employers were seeking from job applicants, but she really got the audience’s attention when she mentioned that her search firm was recently told by one employer that it wouldn’t look at any applicant for a marketing job who didn’t have at least 2,000 Twitter followers — and the more the better. She didn’t disclose the name of the firm, but she told me that it wasn’t Twitter.

At a meeting with students at Fudan University in Shanghai a few days earlier, I was struck by how anxious some of the Chinese students were about the question: “Am I going to have a job?” If you’re a software engineer in China, you’ll do fine, also a factory worker — but a plain-old college grad? The Times reported earlier this year that in China today “among people in their early 20s, those with a college degree were four times as likely to be unemployed as those with only an elementary school education.”

Stories like these explain why I really hope that Obamacare succeeds. Say what?

Here’s the logic: The Cold War era I grew up in was a world of insulated walls, both geopolitical and economic, so the pace of change was slower — you could work for the same company for 30 years — and because bosses had fewer alternatives, unions had greater leverage. The result was a middle class built on something called a high-wage or a decent-wage medium-skilled job, and the benefits that went with it.

The proliferation of such jobs meant that many people could lead a middle-class lifestyle — with less education and more security — because they didn’t have to compete so directly with either a computer or a machine that could do their jobs faster and better (by far the biggest source of job churn) or against an Indian or Chinese who would do their jobs cheaper. And by a middle-class lifestyle, I don’t mean just scraping by. I mean having status: enough money to buy a house, enjoy some leisure and offer your kids the opportunity to do better than you.
