I’m really pissed of this “I’m sad 'cause I’m poor. So if I had money I would be happy.”
(Poverty imply sadness) does not imply (wealth imply hapiness). That’s basic formal logic.

The Contraposition is (not sadness imply not poverty). So, If you are happy, you have money.
Expressed differently, if all the poor are sad, we can state that a happy person is not poor. But we cannot state anything about a rich person being happy or not.

In this case, “I’m sad 'cause I’m poor” doesn’t mean “if poor, then sad”, it means “poor if, and only if, sad”. Logic is about more than symbols.
