At social situations (where pollination between meat eaters and vegetarians occurs), that would make the appeal even tougher. Eating meat then becomes a way of showing off financial status, even more than it already is ("we grilled up this real nice cut of blah blah").

I say this as a vegetarian, but I'm having a hard time seeing cost being a real advantage for imitation meat. It seems like more of a first world problem - if one cannot afford meat, they're better off spending resources on replacing its nutritional value rather than its taste.
