I think that take is a little cynical.

If it's only for the rich then the prices will be high. Meaning the capitalist mechanism of resource distribution will be even higher (more paid by the rich received as income by the non-rich). It will also take demand from existing airlines making fares lighter for everyone else. It also employs people. It also drives technology forward. And ultimately it does let people travel in less time, and why wouldn't we want that? To some extent emissions are not as bad as you'd think since they are being emitted over less time in the course of a shorter journey. Success in this category will also drive competition in every metric and work to bring cleaner, shorter flights to everyone over time.

There is a lot to love about the idea of supersonic flight.

That's not how airline economics work. The first class passengers (the ones who could afford to leave for supersonic) subsidize the economy seats[1]. If they left you would probably see worse prices, worse amenities or both.

There are airlines that don't have business or first class seats (e.g. Spirit), and they're generally a terrible experience.

On the other hand demand for premium seats would be down, lowering their price and making a nicer ride more accessible. Overall this would net to lower prices for the same distribution of amenities on a given plane ride. Supply and demand theory would seem to suggest that equal supply with lower demand leads to lower prices overall. Supply could of course adjust as more people move to supersonic, but that means more people are now getting a better product than before. And if supply of regular jets remains (they're pretty expensive to just have sit there and not try to use for income), lower-end fares and seat availability invite people at the lower end of the resource spectrum to now buy more plane tickets.

Not fully convinced by the "will make fares lighter for everyone else" argument. The economics of planes are heavily weighted towards the passengers up front - business & premium economy make more profit per sqft for the airline than seats at the back. So I'd imagine that a reduction in demand for premium seats could actually increase prices.

The flipside of this is that the passengers in the back, while not as profitable in the "$/sqft" equation, are what merit the airline buying a 777-300 or A350.

If all your focus is on those premium passengers, then you don't need as big an aircraft, and you end up with things beginning to approach JSX's (https://www.jsx.com/home/search) mode of operations.

Emissions are usually compared in amounts per passenger-kilometer.
