I realize that this is getting a bit off topic, but that is an assinine statement to say it is easier to become a teacher or solder than an NBA referee. The only reason it is difficult to become an NBA referee is because of the limited opportunities, not because they have to have some MENSA level of officiating ability. Those individuals who become teachers and soldiers (bless them one and all) do more work, require more certifications and sacrifice more to obtain/maintain their calling than any NBA referee.
Obviously because the pool of opportunity is smaller, the NBA referees are going to be paid more, because the NBA is going to demand (allegedly) a high caliber official. Wanting the best of the best does not come without a price.
But to say that it is a harder and more demanding job than a teacher or soldier and therefore justifiable in the higher pay based on that condition? I call bull . It's not about workload; it's about market demand. If that is what NBA officials can get from the league, then good for them. Supply and demand, free market economy and all that rot. Unfortunately, we live in a society where professional athletes/entertainers are deemed more valuable than teachers and soldiers.
