Eliminating the top 1% of earners is a good policy I support, but I don't think it makes sense as a way to calculate averages.

Though your proposal might work now, in the fullness of time things will change, and the 1% may not be the right number. I don't think you can rely on governments to update numbers promptly. There are places in England that have fines in law defined in denominations that no longer exist. You can't rely on governments keep things up to date.

But your doesn't address the underlying problems with using the arethmetic mean. It seems like you're just searching for justification to pay people you don't like less.

I believe everyone should be able to live comfortably, and well designed incentive systems are effective at shaping behavior. Median is better on both fronts.
