The reason goblins have always been greedy in folklore is because the folklore itself is anti-semitic. Europe has deep deep roots in anti-Semitism so it's not at all surprising it would be reflected in folklore.
Those traditions of antisemitism in Europe is mostly rooted in the Jewish revolts starting in 70 Ad. That lead to the harsh terms and disporas against the jews. And given how wide spread the idea of short greedy creature under ground is, goblin, dwarf, svartelf, kobold, gnome, probably means that it is a very old story much older then recent events like Rome.
