First off, I'm suspect of personal information (salary) posted on the internet. I always expect the number is A) inflated because of pride, or B) understated because they don't want people to know how much they're getting ripped off.
I know one thing, even after being in business for 30 years (6 as employee, 24 as owner) I would like to be making that ratio of $94k/1.2 mil... The fact that he's only 20% owner has nothing to do with his salary, assuming the other owners are happy with the level of profit he is generating for them.
1.2 mil per 12 employees does sound low, but, if they are not actually billing for freight it's basically a service business so it's feasible. 11 employees at $30k each plus his $94 = $425k per year labor, that leaves $775k per year for crating materials, operating costs and profit.
