Supersonic flight will never be suitable for the masses compared to normal flight due to basic physics. It will always require much more expensive planes and more fuel.
It's not more viable now wealth inequality just means that there are more rich people to benefit.

You could have used the exact same argument for normal flight 100 years ago. Supersonic flight being more expensive than normal flight doesn't mean it will always be too expensive for the masses unless you assume there'll be no more economic growth ever.
Relatively, absolutely, but look at computers. Yes, more computing still costs more than less computing. Physics hasn't changed, but the cost of computers has. I have, in my hand, for part of a couple months of middle class wages, more computing power than existed in the world in 1960.
