So how are you calculating how much someone “earned”, then?

You don't know what income tax is? Have you heard the phrase "income tax" before?

You're going to have to ask one question at a time if you want to have a chance at understanding explanations, we're literally starting at the very beginning....

Edit:

Actually...

Who said “we can’t calculate wealth”? Are they in the thread with us?

You did....

I’m not saying it’s impossible, but calculating wealth is nebulous and might not be possible by tomorrow.

Like, right there buddy...

You said it's so hard we can't really do it...
