Because treating people fairly often means treating them differently.
This is something that I teach my students during the first week of school and they understand it. Eight year olds can understand this and all it costs is a box of band-aids.
I have each students pretend they got hurt and need a band-aid. Children love band-aids. I ask the first one where they are hurt. If he says his finger, I put the band-aid on his finger. Then I ask the second one where they are hurt. No matter what that child says, I put the band-aid on their finger exactly like the first child. I keep doing that through the whole class. No matter where they say their pretend injury is, I do the same thing I did with the first one.
After they all have band-aids in the same spot, I ask if that actually helped any of them other than the first child. I say, “Well, I helped all of you the same! You all have one band-aid!” And they’ll try to get me to understand that they were hurt somewhere else. I act like I’m just now understanding it. Then I explain, “There might be moments this year where some of you get different things because you need them differently, just like you needed a band-aid in a different spot.”
If at any time any of my students ask why one student has a different assignment, or gets taken out of the class for a subject, or gets another teacher to come in and help them throughout the year, I remind my students of the band-aids they got at the start of the school year and they stop complaining. That’s why eight year olds can understand equity.
I remember reading somewhere once “we should be speaking of equity instead of equality” and that is a principle that applies here me thinks
“The clitoris is pure in purpose. It is the only organ in the body designed purely for pleasure. The clitoris is simply a bundle of nerves: 8000 nerve fibres, to be precise. That’s a higher concentration of nerve fibres than is found anywhere else in the body, including the fingertips, lips, and tongue, and it is twice the number in the penis. Who needs a handgun when you’ve got a semiautomatic.” —Natalie Angier, Woman: An Intimate Geography
Humankind cannot gain anything without first giving something in
return. To obtain, something of equal value must be lost. That is
alchemy’s first law of Equivalent Exchange.
