Getting hungry happens naturally, so does getting sick. Restaurants and healthcare companies are needed to address each need. The incentives are the same.
Absolutely false.
Getting hungry again happens naturally regardless of the choice of food offered by a restaurant.
Whether you remain sick, are cured, or get sick again depends significantly on the choice of treatment offered. Healthcare companies have an incentive to choose treatments that don't cure you.
People getting sick is not a basic need unless you are a healthcare company. That's why the incentives are conflicting.
