This probably is just culturally different understanding of the phrase, because US corporations indeed feel to act greedy, and there is no similar level of protection of the employees.
However, the thing is, in the long term, the business has to make profits to be sustainable. If the company does not make profits, it will die. Its the short term thinking that breaks down companies. You can maximize profits and be ethical at the same time, if the goal is to do it in the long term.
I do understand that the "maximizing profit for the corporation" is a synonym often for short term thinking and vulture capitalism, but for me it meant something else. This is actually quite fascinating now that I think of it, because this phrase means completely different things in different cultural contexts.
So I guess the trigger is that "maximize short term profits over long term sustainability" is the kind of company where I'd never work for.
