With the Zimbabwean economy in ruins, it is the people leaving the country who are helping those who have remained to survive.
For a country which is in a state of economic collapse, there is a surprising amount of movement in Zimbabwe today.
Drive through the darkened streets of Harare at night - for there is no electricity - and you see hundreds of people walking purposefully at two and three o'clock in the morning.
They are the few who need to get to work - only one in five of the adult population still has a job.
They take up their positions on street corners waiting for a passing car or pick-up truck.
There is no petrol, and regular bus services are already a distant memory.
"I sometimes wait four or five hours to get to work," said one office worker.
"But even the bosses don't complain."
