[MCU] How do you think world leaders managed to not let everything collapse after the snap?

You would think society would completely collapse with half of the population gone, but it seems like the world in the MCU managed pretty well. How do you think they kept everything going until everyone was brought back? The easy answer would be it's just a movie, but I think we can have a little fun speculating.

Having an enemy to blame is probably a big factor. People were not left in the dark to speculate what happened, pointing fingers at each other. They knew it was Thanos. So there would be a sense of cooperation.  

Technological advancements from Wakanda and Stark Industries would help as well. Not having to worry about your lights turning off thanks to your city being powered by an Arc Reactor.   

Captain America probably did a global broadcast to rally everyone together. 

There were still some downsides. Criminal organizations trying to grab up every last bit of power that they could. Ronin dealt with some of them.
