> How does one convince business leaders to bring it back?

There are precisely 1.0 ways to do that: make all of the alternatives more expensive.

That's it. Nothing else will move the needle.

I don't believe it is possible: every policy one can imagine, short of establishing a GULAG system to compel compliance, has powerful opposing interests, including workers themselves. It would require the sort of comprehensive and sustained focus that a nation aspiring to nearly suicidal liberalism can not deliver.
