You're overlooking the main thrust of what I am saying from my top comment to the one you replied to, which is the relationship between Labor and Capital:
> Productivity increases, workers generate more value, but Capital's share of the results increases nonetheless.
To your point, this is even more true for the jobs where productivity has increased the most. Agriculture is vastly more productive today, and the share of profit captured by Capital increases every year. The main point is that productivity gains do not really matter to Labor because the benefits of those gains rarely accrue to Labor.
Put another way: there was a value capture split operant in 1950s manufacturing that contributed to factory jobs being Good Jobs. That split hasn't been operative for decades. In all likelihood, re-shoring factory jobs today would just create crappy sweatshop jobs.
