"Spoiling the Egyptians" refers to Exodus 12:35-36. When the Hebrew slaves were finally let go, they left taking with them many valuables from their former masters: "And the children of Israel did according to the word of Moses; and they borrowed of the Egyptians jewels of silver, and jewels of gold, and raiment: And the LORD gave the people favour in the sight of the Egyptians, so that they lent unto them such things as they required. And they spoiled the Egyptians."
Thus the owner (in the first quote of the thread) who "believes in spoiling the Egyptians" believes in getting whatever he can get.
