Look at the bars in the 2008 recession alone and then compare that to the sum of bars from 2011 until 2018.
We would need another decade of record growth just to offset the losses from 2009. Let alone offset 2008 and all of the loss from 2008-2010 and return to even minuscule net growth over a 2 decade period.
One might think "okay, great, so deliver another decade of growth without a period of recession". Which sounds reasonable until you dig into the reason behind the recent job growth numbers. As the article that you cite points out:
> Baumohl said companies have come to the conclusion that the likely 3% growth the U.S. enjoyed last year was a “sugar high.” With reduced expectations for growth — even with the new incentives to write off depreciation in the Tax Cuts and Jobs Act — CEOs have concluded it’s better to meet the additional growth opportunities with new workers than pricier machines. “Workers are viewed more like inventory,” he says. “If you need them, you can hire them, and if the economy really turns south, you can let them go. CEO have taken a very realistic approach,” he said.
I.e., if you don't produce sustained growth, employees will be laid off. But if you do produce sustained growth, then incentives shift and capital investments in automation are easier to justified. Either way, and regardless of trade policy, don't expect manufacturing employment growth over the next decade to even offset the 2008-2011 losses, let alone return us to net growth over a 20 year window.
