Poor people are poor because they lack valuable labour, land, capital, human capital, or social capital, or because they have disabilities that overwhelm their advantages, or because they squander their advantages, or because they are denied the opportunity to put their advantages to lucrative use (often because of lack of public infrastructure, because of defective legal and economic institutions, or because they are oppressed), or because they are exploited by monopsonists in the markets for their factors of production, or because they are oppressed, or because they are robbed, or because war destroys their assets and the markets for their assets
