Corporate growth is a major culpit. Corporate growth means that corporations open up more HQs and offices and create more jobs in major urban centers. By taking market share away from small regional businesses, corporations are destroying jobs in regional towns and creating jobs in big cities instead. People are increastly forced to move to big cities to find jobs. As more people move to big cities, demand for real estate in those cities goes up. Big cities struggle to increase the supply of real estate due to limited space. By moving to big cities, value-creating workers are increasingly forced to compete against wealthy owners of capital for the limited supply of real estate. Wealthy owners of capital don't need to work for their money, so they're willing to spend a lot more to buy houses that they don't even need; this drives up house prices for everyone else.
