Paolo Maffei sent me a link to this intelligent site - edkless.com. I found this video on there:

It's a good video, I recommend it.

I'd go a step further than the economist there - I recommend you completely ditch the word "fair" from your vocabulary. As in, remove "I only do fair deals" or "This is unfair" or "I try to be fair."

The problem with the word fair is it's completely subjective and almost never adds valuable information to conversation. It's a hazy word that gets in the way of constructive discussion.

Thankfully, it's easy to replace it with more precise phrasings - you could replace "I only do fair deals" (which is meaningless) with "I only do deals that I'd be happy to take the deal from the other side" - which is much more clear about how you evaluate what's "fair" or not.

You can replace "This is unfair" with something more constructive - like, "I'm underpaid relative to people who produce less than me who also have less seniority - I'm going to draw up a proposal for my boss to give me a raise and also for me to produce even more."

See that? That's constructive problem solving, instead of just complaining.

And "I try to be fair" - just scrap that. What's fair? Fair is subjective, and adds no valuable information.

Fair/unfair seems to be more about trying to get knee-jerk emotional reactions instead of doing clear thinking and finding solutions. It's more about trying to rally a crowd instead of fix and improve things. That might be fine for demagogues, but I'd encourage you to clearer thinking - whatever your complaint or position is, there's a way to phrase it while adding more precise and less subjective information. Lay your case out - fair/unfair is subjective and pretty useless for constructive discussion.
