Imagine what would happen if GM and Ford collaborated to invest in the components and architecture of a better public transport network -- and then licensed it for free to cities, states, and countries.
Imagine what would happen if pharma players directly invested in better hospitals and clinics -- instead of in trying to own the relationship with doctors, and furiously outspending one another when marketing blockbusters.
Imagine what would happen if Wal-Mart invested in town squares and parks -- instead of just in featureless warehouses draining what little vitality remains in already bleak exurbs.
