Pete Alcorn used to be a Malthusian. He has a mindset about model of the world: blowing up population and small planet is going to be a bad for inhabitans. The U.N's population data displayed that the trend of population in the world are going to decline. The economist see the decline with stagnatin and depression, but the dwindle of the population have two advantages economic impacts.
Firts of all, a few people need a few land to live in, so, it can reduve land use of slums areas in big cities. Cost of land will dropp and it begins to decline the rate of property. Secondly, a declining population means that job vacancy will incline because the number of population less that the vacancy.
After passing the declining phase, we wiil settle in and start adequate future. The transitions are dangerous phase to pass when the land owners lose their money and labor demand more salary. We carry on the bright future.
