rising above a survival/subsistance level requires access to storage facilities.


e.g


locker
	clothes, cash, mobile phone etc.


house
	furniture, general items


bank
	cash, gold (in the past)

without such facilities (lockable), it isn't possible to increase possessions above what

can be carried from place to place by 1 person.



moveable items

	wagons, animals (camels/elephants etc), items stored in other locations
