The MarketTown is intended as a complete community: the full range of a nation's demographics: rich and poor, old and young - indeed (as in this image) from wheeled-pram to wheelchair. Serving the affluent in New Zealand is easy - they will be attracted to such a high quality of life and have the money and credit to buy. But how do you prevent gentrification - pricing more than half the nation out of the market? MarketTowns proposes to do it by setting aside 20% of the housing in what is called Parallel Real Estate Markets.
The simple example would be a teacher. The average teacher in Auckland earns $60,000 a year, the bank says they can buy a $300,000 home. If the market value of the home is $500,000, then the MarketTown subsidises $200,000 of the home value - they sell it to the teacher for $300,000. When the teacher goes to sell, they can sell for any price, but they can only sell to another teacher. This creates a parallel real estate market that is driven by the restricted earnings of teachers. A complete community needs its teachers to live locally, and creating a parallel market ensures there is always housing for teachers. Of course, the reality is more complex, but this should suffice for a web-site overview.
Why would the MarketTown give up such opportunity costs? Because it is in the interest of its shareholders, the MarketTown citizens, to have a complete community. Not everyone will be high earners. Some will lack skills, others would just rather have a simple job that pays the bills and lets them get on with other priorities in life. Some will be artists.
While this is important in today's economy, as automation eliminates many jobs, this will become increasingly important in the future. The MarketTown creates the local economy, so that basic needs - food, clothing, shelter, energy, social connection and a system of wealth creation and exchange are relatively independent of the evolution of the global economy (which will become increasingly polarised between the haves and the have nots). As such, it is capable of ensuring 100% employment of the willing. When the basics are covered, the new jobs may become more creative, but whatever they become, it remains in the interest of the MarketTown to keep its citizens gainfully employed. It will have the resources to do so.
