You have been hired by AIG, you contract states you are going to be paid a base Salary of $15,000 a year (divided into 26 equal parts per pay period), and a Bonus of 5% of every dollar you bring into the company. At the end of the year you receive on your final Paycheck, 5% of everything you bring in. It could be a ton, or it could be almost nothing, but your pay is determined by your productivity. You brought the company $10 Million of new business, that is $500,000 Bonus. You get, for the end of the year $515,000 in Wages for working for AIG.
The other guy, in the cubile next to you, is hired at $15,000 and the same deal, 5% of what he brings in to the company. He loses $25 Million for the company because his customers left for other insurance firms.
The Company lost $15,000,000 at the end of the year, but handed out a 1/2 Million in Bonuses.
Then, there are people in the media and posters on a site that do not understand the business structure demanding Heads Roll. The guy that did a good job deserves a bonus, the other guys deserves to be fired.
