I've often thought of Taurus as being the main symbol of wealth, its motto being "I have". It is an earth sign ruled by Venus, and represents all that is lovely about the material world. Scorpio on the other end of the zodiac is ruled by Pluto. It's motto is known as "I desire", and its ambitions are often more spiritual than material. It is the side of ourselves that feels like poison about the material world, and wishes to change it. Pluto was in ancient Greece a God of the underworld, but also a God of wealth. Any thoughts on why Pluto is a God of wealth in relation to astrology?
