That's great news, for those 30. Not so great for the 30 other people he could have hired

-This assumes that he could benefit from additional human capital. Maybe he's running at maximum efficiency.

Gravity Payments will be at a disadvantage compared to the competition

-You assume that someone will have to pay extra. He clearly states that he is diminishing his own salary and taking funds from the companies GP dollars to fund this. How does this effect the marketplace? I would assume he knows his company, his product, his projected growth and has calculated how sustainable this is or is not.

• Clerks and service reps will be making far more than they can earn elsewhere

-So what? So what if someone feels a sense of security and doesn't want to leave it. Man, you are grasping for reasons not to like this.

There will be little incentive for formerly lower-paid employees to perform beyond what is necessary to keep their job

My guess is that the employee formerly earning $40k and now earning $70k will be better at their current position. Will they want to move up to another position and work hard to get there? Sure, why not? There are ample studies that show that things like a sense of purpose, the ability to learn and master a new area of expertise and the ability to "move up" are often greater motivators than money.

A clerk that earned $35K must have brought more than $35K worth of revenue to the company

You can't think of employees for a company like this as "rev earning" in all jobs. How do you quantify the amount of revenue a customer service rep brings in? A receptionist? A janitor? You can't. How many home-runs does a pitcher hit in baseball? Not many. So they must not be important to the team, right?
