There are two main types of aid that the rich can provide to help the poor: short-term emergency relief and long-term development aid. Short-term aid focuses on emergency needs like food, shelter, and medicine during disasters. Long-term development aid aims to enhance a country's ability to support itself over time through investments in infrastructure, healthcare, education, and technology transfer that can improve living standards. However, aid is not always effective and the best approach is to help communities help themselves by providing training, skills development, and technologies appropriate to their needs and circumstances.
