If they survive the implosion first off.
Then we are not that close to one and there are some obstacles to overcome. I doubt the Native Americans are going to let anyone on their land.
Then, winter is coming. MANY people seem to have no clue how to dress for inclement weather. I see people all the time in short sleeve shirts and shorts walking around in the snow.
They may think they are impressing everyone with how invulnerable they are, but hypothermia is no respecter of persons.
Then there’s the food issue.
If it ever gets really bad quick, I think there will be a lot of folks who go nuts because they simply don’t know how to entertain themselves without some type of screen in front of them. We have the fattest most passively entertained poor people ever. I picture waves of land behemoths howling in the street for their smartphone to work again.
Good point about weather. Our poor people are used to climate controlled environments and unused to hard labor outdoors and in all weather.
