Build That Wall

The Year 2063 - After long and extensive lobbying by high-strata-consumer groups under the guidance of the Swedish 'Happy Corporation' general legislation was ratified in Eurasia to privatise public spaces. This move, it was argued, had become necessary to protect the interests and safety of the high-strata class due to uncontrollable and ever growing utilisation of space by expels and low-strata-consumers in areas traditionally not suited for them.
This, too, seemed to be a late consequence of the migration crisis of the early 2040s. Swiftly structural changes were being implemented in urban developments and topographies.
The 'Happy Corporation' became the main supplier for privatisation equipment ranging from 'Spikes' (electrically charged steel barriers) to face-recognition surveillance drones, called 'Parrots'.
