Do you think “work” means literally “manual labor”?
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”.
