Down and Out in Paris and London

Orwell was down and out in London, going from spike to spike. (Spikes were homeless shelters. You would pay for a bed or in some cases just a cell. You would have to be there for a mammoth long time, doing absolutely nothing.) Orwell calculated that each day England's population of homeless people spent ten years staring at walls.

The two main problems with homeless people were: they were idle, they were hungry.

The solution is obvious: make them grow their own food. Turn all the spikes across the country into vegetable gardens with accommodation. You don't have to pay to get a bed (or cell); you have to do a bit of gardening. Then you can have some nutritious veggies and some sleep.

Solving those problems solves yet another problem: their general health, which was appalling, as they had no fruit or veggies in their diet.
