I think neocolonialism happening today is also considerably more efficient at stealing wealth

Our results show that in 2015 the North net appropriated from the South 12 billion tons of embodied raw material equivalents, 822 million hectares of embodied land, 21 exajoules of embodied energy, and 188 million person-years of embodied labour, worth $10.8 trillion in Northern prices

For instance, 21 exajoules of energy would be enough to cover the annual energy requirements of building out necessary infrastructure to ensure that all 6.5 billion people in the global South have access to decent housing, public transport, healthcare, education, sanitation, communication, etc. (Kikstra et al., 2021a). Eight hundred and twenty-two million hectares of land, which is twice the size of India, would in theory be enough to provide nutritious food for up to 6 billion people, depending on land productivity and diet composition (Poore and Nemecek, 2018).
