If you don't like it, talk to Gene Roddenberry. In ST:TOS the Klingons (IIRC) were used as a stand in for the Soviets:

Or you could view it as the anthropomorphization of the vice of greed or stinginess/miserliness/parsimony.

Heh. You wanna guess where my ancestors come from? :)

Most fiction tends to be based at least in some part on reality, whether the author explicitly intended it or not (allegorically or literally).

We learn from fiction. Try it. And... It's fine if you find it offensive. We don't care.
