Almost all large, modern, public businesses are engaged in a pump and dump scheme where no one making decisions has any intention of being around for these last phases of corporate decay and death. It seems nuts to us from the outside and is super damaging to the long-term interests we all have in the US but this is taught in business school and is in fact the right business decision for these people to make given the context and sociopathic motivations they operate under.
No US business school teaches pump and dump schemes. The fault lies with corporate boards who set up compensation plans not aligned with the interests of long-term shareholders. It's the basic principal / agent problem.
Ok ok schools don't literally teach that, true, I was ranting but "corporate boards who set up compensation plans not aligned with the interests of long-term shareholders", is a pump and dump, exactly my main point, which stands.
