Product design will continue to accommodate automation in manufacturing. So never say it can't be done.
Affiliates have already suffered from automation and anyone who doesn't see it taking over more is a fool.
Whatever's left won't be enough to keep 30% of the population in a job that pays well enough to support a family.
And there's the problem.
A Car Production Plant that used to employ 1,000s now employs 100s. The worker's incomes are not 10 times the previous worker's wages. That means tax revenues have been reduced by a huge amount. Making 50% unemployed means they need benefits to keep them clothed, housed and fed. Which is hard to find when Tax Revenue is harder to find.
Add Globalisation, Population increases and you have a Perfect Storm for a revolution.
This is the future and more people than me are stating it.
