It all depends where they are flying into and out of and who serves the routes as well.

A Gulfstream costs around 50 million USD or more, plus captain costs and fuel costs, and other expenses. However Gulfstreams are usually owned by corporations and the owners are big money corporations but the executives who fly on them may or may not be billionaires.

Billionaires also own their own planes outright including various plane types including jets also used in commercial aviation and I wouldn't be surprised if they owned business class jets too on their own.

Carbon fiber aircraft tend to be the lowest cost and a few firms were working on low cost aircraft, which as we know is also being used on the Boeing 787 project. The cheap carbon fiber jets are known as VLJ (very light jets)

Gulfstreams are one of those business jets with a great reputation.
