College Graduate chessmaster or Super GM Dropout

Hard to think of a good title, i'm mostly curious about income, i mean.

Assuming almost equal income for both sides

like

Almost all of your income from college degree/ or being a sucessful business man + a little bonus from chess by being FM / IM level ( and also has the title)

OR

at least 2700 Super GM level that lives off doing chess stuff

Or to put it in another way

Some kind of business/engr/doc /etc guy who almost makes the same amount of money as magnus carlsen + has FM / IM title

OR

Magnus Carlsen

Hope you guys understand what i am trying to say :P

I'd rather be that guy that has FM / IM title + sucessful college grad because being SGM seems like alot of work even if i had the skillz lol
