Great point. Money is vanity! Until is needed, of course. :)
You found a metric that rules all workers: $/free-time.
Some reflections can be made about if is “free-time > working-time” or about how to create “free-time = working-time”.
Trying to apply here. A doubt here:
“Monthly Net Income/Monthly FreeTime Ratio = Bad>10<good”
How do you calculate Monthly FreeTime Ratio?
A did my math here, I’m in a bad situation. :O
