Folding in a collection pot

[Bicycles_Biatch]

for those of you who are familiar with the collection pot theory (talking players into the idea that the first pot over x dollars pays everyones collection for the hour and/or half hour)...

I need your help on an argument I'm having with a friend.

He feels that if you're playing short in a NL game (with no max) that has a collection pot... you should be open folding hands like KK or QQ under the gun during that collection pot.

His argument was that with an effective $150 rake... if you're playing relatively short ($600-$700, like some people do at commerce)... you're negative EV to play the hand... I obviously disagree... thoughts?
