>I also predict that meat substitutes, if made cheaper than meat, will be deemed inferior in quality (cheap = inferior, because psychology) and reserved for those who cannot afford real meat (the "meatless masses").

I think there will be such a period, but eventually it'll swap.

Both because more affluent people will tend to be more pro-animal welfare and so synthetic meat will be more associated with the successful, and because eventually (probably distant future, but who knows) all the meat substitutes will just taste better than real meat and anyone who's ever had a meal won't be able to deny the reality.
