At their heart, the left believes the economy is a zero sum game. If someone gets richer, they had to have taken if from someone else, probably by cheating or exploitation. They don’t understand that in general transactions benefit both parties involved. That’s why they focus on redistribution and “fairness” instead of creating more wealth. And why they are obsessed with how much others have.
That's why we need to take back "fair trade" from the Leftists. They stole our term and forced theirs ("capitalism") on us.
We don't have to play along.
