Yes, he enjoyed it, why wouldn't he? Nash "running the place" revolved around everything being done the way he wanted, a condition which surely does make a person happy.
If I read it correctly, Nash worked on a personal services contract rather than one that most wrestling performers operate under, which enabled him to collect his big salary whether he worked or not. While that might be terrific for him, can you imagine the tension it would create in the locker room among performers who weren't as "contractually fortunate" as he?
This was WCW. They threw cash around like Monopoly money, but I doubt they did it equitably.....and the differences between the "haves" and "have-nots" were probably so enormous that tensions in the Middle East looked like a love-in by comparison. Plus, those with personal service contracts likely skirted a lot of ring and publicity duties, leaving the "have-nots" to work double time to fill in.....which created further resentment.
Yes, any organization (sports entertainment or not) is going to have people who are unsatisfied with their working conditions, yet WCW seemed to go out of its way to create a bad situation, starting mainly because they had too much money for their own good.
