Well, it's about marketing and positioning isn't it. Veggie based diets are plausibly healthier due to higher content of fiber - and health is generally considered an admirable trait. So the marketing should not be about selling a cheap offering, but something like Coca-Cola (everyone likes it!) and celebrities enjoying the product and so on. A campaign that draws everyone to the product basically (like cigarettes in olden times). I'm not sure if you can achieve something like that today though. But at least US food industry used to be really great at selling a cheap product to the masses if they put their marketing muscle behind it :)
