From Robert Whitcomb’s “Digital Diary,’’ in GoLocal24.com

Last November, Bill Gates predicted that half of business travel and 30 percent of “days in the office” would disappear forever. Meanwhile, the McKinsey Global Institute says that a mere 20 percent of business travel won’t return and about 20 percent of workers might be working from home indefinitely. Whomever you believe, all this means far fewer jobs at hotels, restaurants and downtown shops, even as the pandemic has speeded the automation of (i.e., killing of)  many office jobs  (including home office jobs) and  more factory jobs.

So what can government do to train people for new, post-pandemic jobs, assuming that  there will be many? How can vocational and other schools be brought into this project? The trades – electricians, plumbers, carpenters, roofers, plasterers, etc., will probably have the most secure, and generally well compensated, jobs going forward, along with physicians, dentists and nurses as well as engineers of all sorts and computer-software and other techies.

Another part of the jobs package should be a WPA-style program to rebuild America’s infrastructure, which the drive for lower taxes and higher short-term profits has dangerously eroded. (See Texas again.) This has undermined the nation’s long-term economic health. Such a program could also serve to train many people in new, post-pandemic skills that would be useful even as automation accelerates.

Of course there will always be jobs available for very low-paid personal-help people, such as home  health-care workers. Indeed, the aging of the population means that we’ll need a lot more of them 

Andrew Yang,  an entrepreneur who ran for the Democratic presidential nomination in  2020, made  addressing the looming threat of automation-caused job losses a key part of his campaign, which he suspended before the pandemic. He has proposed giving Americans a $12,000-a-year “basic income’’ to help get them through the developing employment implosion. It may come to that….

Meanwhile, “meds and eds’’ – Greater Boston’s (of which Rhode Island is on the edge) dense medical, technological and higher-education complexes – will help save it at least from the worst of the long-term economic disruption caused by the pandemic. Much research must be done  by teams in labs; technological breakthroughs require a lot of in-person collaboration, and most college students will continue to want and need in-person teaching. Further, Greater Boston is an international venture-capital and company start-up center. These high-risk activities also require a lot of in-person, look-‘em-in-the-eye work.

On the other hand, Boston’s banks and its famed retirement-investment companies, such as Fidelity, will never have as many employees working in its offices as before COVID-19; nor will its innumerable law firms. Many offices in high rises in downtown Boston (and Providence) will remain empty for a long time while architects, engineers and interior designers try to figure o
