Indicate whether the situations involve economic discrimination. Sharna lives on a planet where unobtanium is mined by an interplanetary mining consortium. As such, many different kinds of aliens visit Sharna's planet to work. Sharna has found Earthling poetry and prose to be the worst drivel. Thus, Sharna refuses to purchase any Earth products. Sharna refuses to sell any goods to an Earthling. Sharna will loan Earthlings less for business loans than any other startup owner because of her displeasure from reading Earth literature. Sharna's business is a monopoly. Because laws on the planet are lax, Sharna conducts price discrimination based on each person's ability and willingness to pay.
