If billions of people are resurrected, you're going to need mass-production of clothing, food, shelter, etc. Mass production = assembly lines, shift work, etc. Again, who gets stuck with those crappy jobs? And why them?
How will the G.B. be able to control everybody on the planet ? TV`s ,P C`s ,no electricity and if you do have these things you need materials and factories to produce them and infrastructure roads and transportation to get them to everybody .
The printed paper such as books and letters etc.? Again you need paper,ink , machinery,power etc,etc.that needs to be manufactured by a workforce and again transport is a problem because there will be no ships to cover the seas ,no airplanes to fligh across oceans and if they existed they would also need a workforce to operate them night and day.
And without all of the mod cons we all take for granted today to be gone Paradise would soon become a living hell here on earth.
