We never really saw what the snap did to other people outside of the Avengers circle after the events of Infinity War, but as the heroes, it wasn't easy, which made the first act of Avengers: Endgame so bleak.
The main goal of Captain America and company was to reverse the snap, but Screen Rant thinks they did not stop to look what it could do to the world.
In Avengers: Endgame, five years passed before the snap was successfully undone. The world likely descended into chaos after the apocalyptic event, forcing what's left of humanity into panic and eventually survival mode.
Ultimately, these people, like the Avengers, had to go on with their lives after the overwhelming loss. However, now that the dusted people have returned to the same place where they vanished at the same age they were they were first dusted, the impact on the personal lives of those who experienced the devastating effects of the loss is crazy.
Screen Rant can't help but imagine a lost girlfriend or husband coming back only to find their significant other already with someone else. Babies who were left will be five years old by the time their dusted parents come back. At that point, they may not have been found and unable to survive or have been raised by other survivors. A snapped sibling older by five years will end up being younger than the actual younger brother or sister who survived the snap. Government leaders who were turned to ash return to find other people taking charge.
As the rest of the world copes and tries to rebuild again, the other half of all life sprouting back will cause problems. Within five years, the site posits that humanity should have already found a way to grow their own food resources and devise new methods to establish food supply.
Bringing back billions of people at this point as it was done in Avengers: Endgame would worsen the food shortage, the site suggests. Not to mention that the population of trees, plants, and animals were cut in half too. By the time they are snapped back to the original places from which they were erased from existence, new establishments may have been built there already.
As evidenced in the Spider-Man: Far From Home trailer, however, it doesn't look like the world is struggling. In fact, the actions of our heroes in Avengers: Endgame brought things back to normal. So it looks like we won't be seeing the logistics side of things involved in the reversed snap.
