What do you mean “extracted”? The wealth is sitting there in his 401(k) being risked through (highly) fractional ownership of various publicly traded business ventures.
Please provide an example of how logging in to fidelity.com to see that today my net worth increased by a multiple of my annual salary constitutes "work". Define your terms so it's clear to readers.
Are you sure you tried to come up with a counter example?
If the only kind of “work” is “selling your labor” then sure, but I think a farmer tilling his own soil is “working”.
I described it as “sitting there” to contrast my viewpoint that in fact it’s not being “extracted” from anything as far as I can tell.
It’s totally incoherent and unreliable as an explanation for an economy, but it explains the comments in this thread.
