In 2040, I would like to see housing become a human right and to see every human being housed safely and securely. This housing would be guaranteed despite income or employment status. Houses would become affordable through 3-D printing materials and through government social housing schemes, housing lotteries and affordable mortgage schemes. Houses could be owned or rented but everyone is housed. Derelict houses will be renovated and vacant/hoarded properties will not be permitted by landlord. Air BnB will not be allowed post full apartments or houses (only rooms in-house like normal BnBs). This economic and social security would boost local and cultural economies. The cities will belong to the people who live, work, and care there not to multinational corporations or to tourists (though tourists are of course welcome).
