Filthy Wealthy

Filthy rich sounds right. Filthy Wealthy doesn't.

Where does the saying filthy rich come from?! I know money, the actual metal or paper has been through a thousand hands and maybe some toilets (the metal ones), but what does filth have to do with rich?!

Filthy is not just dirty. Filthy also means obscene or morally foul.

A poor person must have assumed all rich people were morally unjust. Or maybe a jealous person.

Rich is a great word. a noun and an adjective. Means full, intense, abundant, complete, thick, dense, creamy, opulent, luxuriant, not just the state of owning many possesions and a large bank account.
