A Technical Question Regarding Blind Stealing

[David Sklansky]

In reviewing an upcoming two plus two book, I have come across a statement that I believe to be incorrect (and if so will change). It has to do with how many hands are profitable raises on the button or small blind, given the tightness of the big blind. Playing Limit Holdem

Obviously, as a general rule, the tighter the big blind, the more hands you can profitably raise with. And vice versa. But what about if the blind is extremely loose? Is there some point where you can add back in some hands as profitable raising hands (assume you can't just call) that you would fold if he was a tad tighter? We can make this question a litter more explicit later on if need be.
