In the Avengers the villain snaps his fingers and half the universe population disappears. Later, after several years have passed this half returns, effectively doubling the world population in one moment.
Is there any in-universe explanation of what happens in the mid-term after this? It seems to me that this would be an event with catastrophic consequences. The economy could hardly absorb an immediate doubling of people and it seems unlikely that the world, while struggling to cope with their loss a few years earlier, would have stockpiled 2x the annual food consumption.
In the real world I live in, I would expect global riots, food looting, famine, war, and widespread starvation. But in the films the only problems they address seem rather minor in comparison: emotional support groups and occasional disputes over home ownership.
What actually happens in the Avengers universe after the world population is immediately doubled?
