Well, the people being charged the most, white males, did not complain. YOu cannot say that: the total sales were $1.50.
The people being charged the least, females and people of color, were the ones complaining.
They were not complaining about the price but abotu the race-based pricing (public good). All people should've complained about that, regardless of whether they benefit from a particular sale (private good).
It's a just another club on campus, raising awareness of a very political issue.
Raising money for a political club is not a "busiess."
At any rate, the people complaining were not overcharged for the donuts, so there is no harm done to them.
The college administration was wrong on this, and I suspect the College Republican club will outsmart them again in the near future.
