You assume people will act fairly if you act fairly. They won’t. People act in alignment with their incentives, not your expectations. If the structure rewards selfishness, selfishness appears.
Here's some food for thought:
Last year, about 100 women died at childbirth in UK🇬🇧 .
In Norway 🇳🇴, not a single woman died at childbirth last year.
In contrast, 75,000 women died at childbirth last year in Nigeria 🇳🇬.
This. Is. Not. Acceptable.
