Episode notes
Include Distant Strangers In Moral Consideration
- Treat distant strangers' welfare as morally relevant because they can experience well-being or suffering.
- Singer argues distance doesn't change intrinsic value; technology now often removes ignorance about distant needs.
Give To Effective Poverty Relief Where Dollars Go Far
- Donate to reduce extreme global poverty because marginal dollars do far more good there than for affluent donors.
- Singer cites examples like corrugated roofs, malaria nets, schooling transforming lives for ~$1,000 per person.
Use Individuals Companies Or Governments To Fund Poverty Eradication
- Pursue aid via individuals, companies, or governments; all can contribute to ending extreme poverty.
- Singer notes a 10% tithe of global corporate profits (~$10T profits) could roughly fund bringing everyone above extreme poverty.
