For the benefit of society.
Why do we exist? Surely, not to do taxes, take out the garbage or do any of the other millions of things in between living. Life is meant to be lived well; not spent in doing chores.
To that end, governments, corporations, and other public and private institutions should exist to improve life for all. That should be their number one priority. One could argue that that is the way things are today. None of these entities work to make life worse for people.
But, the fact that these entities, on the whole, improve lives for people is a by-product of their desire to fulfill their own needs. For corporations, it is making money. For government, it is for the politicians to stay in power (whoever heard of a politician stepping aside because another candidate was a superior choice?).
Some organizations are truly altruistic. Public libraries, schools are examples. However, they hardly get the respect and resources they deserve to be truly successful.
In my world, it will be mandated that all actions of all entities should increase the standard of living for everyone of its citizens.
You know what that means, right? No more cigarette companies.
