Hi!
Conversation:
Rich man: I am rich, and you are poor. I’m richer than you and you are poorer than I. In fact, I am the richest person here and you are the poorest person here. Poor man: So what? Rich man: So, I have the most money and most dollars and you have the least money and
the fewest dollars. Poor man: Again, so what? Rich man: So I live in the largest most expensive house and you live in the smallest least
expensive house. Poor man: Why? Rich man: Because I am the richest man in the world. Poor man: Yes, but I am tall, and you are short, and I am thin and you are fat,
and I am nice, and you are nasty. ← Rich man: So what? Poor man: So, I am taller and thinner and nicer than you, and you are shorter and fatter
and nastier than I. ←
I simplified the last line for clarity:
“You are nastier than I.”
As I understand it, using “I” at the end of this sentence is absolutely correct.
It’s also something people would very rarely say. I think most listeners would hear it as an anomaly.
You are more apt to see or hear “You are nastier than I am.” This is also grammatically correct.
Or, more commonly, “You are nastier than me.” Not grammatically correct, but more common than the others.
I’m glad you posted this conversation, because overall, it illustrates the clash between materialism and personal virtues, and how different people prioritize different aspects of life. It also underscores the idea that wealth isn’t the only measure of a person’s value.
In the Name of God, the Compassionate, the Merciful.
