A 'money zombie' is a person who exists and lusts for 'money' --- they are severely intellectually stunted and emotionally dead.
A 'money zombie' is a person who only predominantly considers society from economic and monetary perspectives, and they lack empathy.
A 'money zombie' is so cognitively impaired that they cannot meaningfully appreciate society from emotional, natural, physical or any other perspectives, and they always need more money and more stuff to exist --- they are not content unless they are earning, profiting or consuming. They will never experience or know true happiness, love or joy.
A 'money zombie' always need more MONEY and more STUFF, and if this greed drive ever stopped, they might actually come back to real life.
