You are being downvoted, but I think that you are totally right. For an awful lot of people, eating meat is a matter of status; it's similar to why many people prefer having big cars even if they are less environmentally friendly.
There is also the fact that plant based diets are still associated to certain ideologies and because of that they will keep being scoffed at by people from opposing ideologies. Sure, you don't have to lean left to be vegan, but the vast majority of vegan people, or people seriously trying to reduce their meat consumption, do lean left (continuing with the car analogy: remember the rolling coal fad).
Dietary choices go way beyond their nutritional value. People feel attached to what they eat, and they will resist change. So, yes, a strong economic incentive is needed, and even worse, it might not be enough.
