Pareto

Don't be frustrated with the mathematics and statistical jargon. Our original question was simple: If we accept not all men are equal and there is always a certain degree of uneven distribution of workload, how uneven a distribution should we consider not acceptable - or not expected under normal social circumstances?

Yes, it becomes a philosophical question. Nonetheless, I suppose we have a convenient solution at hand.

Let's follow the Pareto principle.

Oh, I scared you by the jargon again. The principle is also commonly known as the 80-20 rule.

For example:

• 80% of the your effort is spent on 20% of the patients
• 80% of what you learn in a medical school comes from 20% of the curriculum

And, here, 80% of the urgent endoscopy requests are covered by 20% of the endoscopists.

Maybe we have to accept that's life.

PS. Mathematically, when something is shared among a large number of people, there is always a number x between 50 and 100 such that x% is taken by (100 − x)% of the participants. The number x may vary from 50 (in the case of absolutely equal distribution) to nearly 100 (i.e. one winner gets all).
