This is way too complicated to give some simple guide...the best answer we could give is that you shouldn't 3-bet all the time or call all the time...it depends on so many factors. I think your friend overestimates bad players' calling range (even if you're a nit and 3-bet rarely). He also is probably overestimating their ability to play in big pots. Plus, the more often you 3-bet, other players widen their 3-bet calling range + 4-betting range. Your friend is basically making it far too simple. It's something you are going to have to develop on your own based on hands at the table.
