The challenges facing a developed country include:
- Dramatically reducing their impact on their environment, particularly through greenhouse gas emissions (see global warming), with affordable political and economic cost.
- Avoiding incentives to pollute such as fossil fuel subsidies.
- Maintaining security - ideally through creating a world in which all countries and all people have a stake in the shared prosperity, and thus have a shared interest in peace and cooperation.
- Aiding poorer countries achieve prosperity sustainably, for example through ending agricultural subsidies and carefully targeted foreign aid.
