Possible Stupid Question: If Business class and Premium Economy are the real moneymakers, why don't airlines focus on them?

Basically what the title says - I've often heard that Business Class and Premium Economy are what actually makes money for the airlines and that they oftentimes operate First and Eco Class at razor thin margins or even losses. That begs the question (at least to me) why some airlines don't cut out Eco entirely and only cater to higher end passengers.

I've heard of some niche cases of Business-only flights, and understand why they might want to keep First Class (Associated prestige, retaining Brand loyalty by keeping the opportunity for people to upgrade etc...) but operating less profitable or unprofitable Economy class out of "altruistic reasons" and "making airtravel available to the masses" does not make sense in to me in my (granted very limited) understanding.
