I covered the Republican convention, and I was impressed in watching my Times colleagues at how much their jobs have changed. Here’s what a reporter does in a typical day: report, file for the Web edition, file for The International Herald Tribune, tweet, update for the Web edition, report more, track other people’s tweets, do a Web-video spot and then write the story for the print paper. You want to be a Times reporter today? That’s your day. You have to work harder and smarter and develop new skills faster.

Van Ton-Quinlivan, the vice chancellor for work force and economic development at the California Community Colleges System, explained to me the four basic skill sets out there today. The first are people who are “ready now.” That’s people with exactly the right skills an employer is looking for at the right time. Employers will give the local labor market and schools the first chance at providing those people, but if they are not available they’ll go the “shortest distance to find them,” she said, and today that could be anywhere in the world. Companies who can’t find “ready now” will look for “ready soon,” people who, with limited training and on-the-job experience, can fit right in. If they can’t find those, some will hire “work ready.” These are people with two or four years of postsecondary education who can be trained, but companies have shrinking budgets for that now and want public schools to do it. Last are the growing legions of the “far from ready,” people who dropped out or have only a high school diploma. Their prospects for a decent job are small, even if they are ready to “work hard and play by the rules.”

Which is why if we ever get another stimulus it has to focus, in part, on getting more people more education. The unemployment rate today is 4.1 percent for people with four years of college, 6.6 percent for those with two years, 8.8 percent for high school graduates, and 12.0 percent for dropouts.

That’s why I prefer the new mantra floated by Clinton at the Democratic convention, (which Obama has tried to fund): “We have to prepare more Americans for the new jobs that are being created in a world fueled by new technology. That’s why investments in our people” — in more community colleges, Pell grants and vocational-training classes — “are more important than ever.”
