I have much money than you.
I have much money compared to you.
Is there a diference between the two sentences?
The first sentence should be: "I have much more money than you."
The second sentence should be: "I have a lot of money (when) compared to you."
The difference is that the first sentence directly compares your money with mine. The second sentence uses your money as a reference point to judge whether I would be considered to have a lot of money. It is a subtle difference - the essential meaning is the same in both cases.
