I put on stone? Some would some call me bloated! (10)

Ross

I believe the answer is:

capitalist

I'm a little stuck... Click here to teach me more about this clue!

'some would some call me bloated' is the definition.
I can't tell whether this defines the answer.

'i put on stone?' is the wordplay.
'put' becomes 'capital' (I am not sure about this - if you are sure you should believe this answer much more).
'on' is a charade indicator (letters next to each other).
'stone?' becomes 'st' (abbreviation).
'i' after 'capital' is 'capitali'.
'capitali'+'st'='CAPITALIST'

Can you help me to learn more?

(Other definitions for capitalist that I've seen before include "investor" , "Free enterprise supporter" , "Profit-driven person" , "business person?" , "Seeker of profit in business" .)
