A G-IV is a very expensive airplane to own and fly as an exclusive private airplane (as opposed to fractional share, charter, etc.)
The owner, Lewis Katz, wasn't known for skimping on anything. He didn't have to. He previously co-owned YankeeNets along with George Steinbrenner. That's YankeeNets as in the NY Yankees baseball team and the (then) New Jersey Nets basketball team. They also owned the New Jersey Devils NHL team. Katz was also the co-owner of The Philadelphia Inquirer.
Both of the pilots were very experienced and took the G-IV PIC Recurrent course at Flight Safety annually (which costs an arm & a leg).
The PNF that day had worked as the personal pilot for Mr. Katz for 27 years. He had 18,200 hours logged, with 2,800 on the G-IV and another 4,700 hours on G-II/IIIs.
The PF that day was also a long-time employee (12 years) with 11,050 hours including 1,400 on the G-IV.
Similarly the flight attendant had worked for the Katz family for over 15 years.
Those long service years are indicative of a well-compensated crew. I'm sure the owner felt they were among the best in the business.
I think in this case, the owner probably did all that could be expected from a (non-pilot) owner.
