If you said 'The poor are worse', you'd be open to the question "Worse at what?"The report details the slope linking income and health: The poor are worse off than the less deprived, who in turn are worse off than those with average incomes. This "social gradient" is seen everywhere, including the most well-off countries like Canada.
Can I remove the 2 first "off" and preserve the meaning of the sentence, please?
If so, what is the function of those 2 first "off" in the sentence?
The reason would be clearer if the writer had been more consistent with the hyphen. There are two contrasting terms: "badly-off" and "well-off."
As to the third "off", it is part of an expression that mean "lucky", right? It means "prosperous", so in some contexts it can have the connotation 'lucky', especially in the context of someone not knowing when s/he's well-off.. . But usually well-off doesn't mean lucky; King Midas was well-off but he wasn't lucky: Midas - Wikipedia, the free encyclopedia
Can I say that the usage of the 3rd "off" was only a matter of style, that is, the writer just wanted to look clever and harmonic with the rest of the text?
No, he was saying what he meant.
