If not due to their articles, then what cause do you attribute that widespread outcome among traded, subsidiary, et al. corporations to? (I’m happy to be wrong but it’ll take some time to research this and I want to be sure to hear your opinion in the meantime.)
The CEO and other execs will get paid more if they increase profits (usually in the short term). But that's very different than your claim that the articles of incorporation force them to do it.
