That's assuming that corps (& customers) are rational. If the former decide to go purely for profit, & devil take the hindmost, we get
Big tobacco, which happily sent customers/victims to pain, suffering & death
Big pharma, which happily wrecked individuals, families, communities to addiction, depression, violent crime, suicide
Big oil, which is happily still reaping big profits, & slowly tightening the noose around the neck of the World
If these corps were persons, we would count them as psychotic, & likely remove them from the public sphere, to protect society & themselves from further harm.
