Malthus was actually 100% correct, except that he did know that fossil fuels would be discovered underground that would allow humans to consume millions of years worth of stored energy in just a couple of hundred years. This allowed humans to explode in population with massive industrial farms and advanced technology in all fields of endeavor. Now that the years of fossil fuels are coming to a close, prepare for Malthus to be correct again. The Earth will need to gradually get back to 1 Billion people, and that will be painful in many ways to our species. Meanwhile, we should change the tax system to be more fair, and gain more revenue from the most wealthy in society, and then use that money to try to engineer the transition to technologies, transportation and cities that do not rely on fossil fuels.
