I'm a bit bemused by that comment: I can't think of many jobs other than being a celebrity, that provide both the income and free time needed to fly regularly. All of my friends in the professions (medicine, law, finance) are worked to the bone.
What I was thinking of is that a full time working media person is not going to have a huge amount of time, despite having loads of money. Big-name actors like Travolta or Cruise work flat-out when on a movie (several months?) and the rest of their time is theirs. Travolta would have spent loads of time getting his (IIRC; one can look it up on faa.gov) CPL/IR and his type ratings.
Normal working professionals tend to have little time, as you say. Throw in a 1hr+ drive to the airport (pretty common if you live in London) and it makes GA even less attractive.
