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.
What are we talking about? 5% more? 200% more?

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.
There are 28 000 passenger flights in the US every day, imagine the noise under major corridors if a large percentage of them was supersonic.
