I'd say that, at very least, a pro player should be on equal footing as a middle class person earning $50,000 + bonus + medical, dental, and retirement benefits. Perhaps that's about the equivalent of $90,000 with no beneifts of any kind. Still, the pro player surely has $15,000 in expenses, so let's make that $105,000. Also, the middle class worker making $50,000 has both disability insurance and unemployment insurance. Better make that $120,000 in gross earnings to be on even footing. Add in a year end bonus of $5,000 and we're up to $125,000, and that's without profit sharing and employee stock ownership plan benefits.
Still, in the long run, the worker earning $50,000 plus bonus plus medical, dental, retriement, disability and unemployment benefits is better off than the pro player earning $125,000, because the worker is developing marketable, transferable skills, that make continued earnings growth likely over time. In contrast, the pro player is developing nontransferable skills that fade and, ulitmately, disappear over time.
Also, employees are often entitled to partial or full pay even when they don't work in certain situations such as a) Family and Medical Leave Act absences, and b) when they serve jury duty. Finally, employees are entitled to a certain amount of severance pay if their employment is terminated.
I feel strongly that the worker earning $50,000 plus full benefits would be trading down if they went to the IPT and earned the alleged minimum of $100,000 in 2007.
