It seemed fairly obvious that the main problem with humanity was temperature. The top and bottom of the land was cold and the middle bit was too hot and covered in sand. To make this all work as an empire, the easiest thing to do was move the populace to the nice green bits. The hot bits would still be useful for generating electrical energy as power was high on the list of needs.
"You can't make good cupcakes with bad ingredients," said Pink.
Humanity was difficult to herd though. You couldn't have them running around just anywhere, all angry and sad. Multi media had proven such a great way to keep every one content and balanced that there was no reason to change it now. But how to keep everyone where they should be?
They argued about this for hours, before taking a lunch break and coming back for another debate. Orange suggested a big critter proof fence which; sounded really good, but the math didn't add up. They couldn't get workers to build a huge fence and grow enough food for everyone in any reasonable time scale.
Yellow suggested asking them nicely and then shooting transgressors, to basically reward the obedient ones with a long and prosperous life. This looked like a very good solution indeed! They had already seen that there were plenty of people out there who would shoot just about anything if given a gun. But it was still resource hungry so they decided to simply make the less nice bits a bit less nice. They would jam communications, cut the power, cut any water supplies and send any local government into hiding if they didn't help. They'd be grateful later on, when they were living somewhere pleasant.
Starting a mass migration was no easy task though. Their new world plan did have some advantages. An awful lot of time was spent on the logistics of a consumer lead society. From now on more folk would work on the land. Their food would be right in front of them. And after a good healthy days work they wouldn't need to go to the gym.
Things really started to make progress when the ponies took control of the banks. Now they could make it an economic migration! Of course, anyone could work at whatever job they liked. This wasn't slavery after all, it was just organising. They could get up in the morning and sit at any desk they chose. But at the end of the month there was no money paid into their bank account. Complaining to the bank didn't help. Only designated jobs paid a wage.
Soon trains were running out of the cities full and coming back empty. While within the conurbations huge gangs stripped any suitable materials they could find from buildings. Lorry loads of bricks and beams made their way to countryside locations across the world. It was common to see a cell phone mast roped on top of one so that even the most isolated communities had their 'tech' working properly.
Not that this wasn't without it's risk to the populace. Office staff were not accustomed to the physical work or the risks of demolition. All too often screams were followed by the sound of a building collapsing. Then came the familiar city sound of an ambulance making its way through the streets.
While the cities and large towns were plundered, the exact opposite was happening around them. Big farms now became small villages. Factories that made cars now made hand tools for working the land. The enormous cargo ships that carried food around the globe to hungry nations now moved the nations to the food. The need to balance the resources of the new age was intensive.
The behind the scenes choreography was even more impressive. Purple had compiled the family tree of everyone and used it to their advantage. Now families who hadn't seen each other for decades found themselves living in shipping containers next to each other. The MLP archives had shown her how important family was and it was now a corner stone of making the project work.
