What happens when all the people who perform routine but necessary work to keep the lights on (coal/nuclear/whatever) are dead / dying / quarantined at home?

What happens when the water main breaks and no one comes to fix, because everyone living went to college for underwater basket weaving gender studies or played sports or just sat back and collected a cheque from the government

What happens when the trucks stop delivering the food to the store?

We were probably due for another dark ages and here we stand at the door
