I have.
I've seen a family of four, living in a shack smaller than my first apartment.
I've seen people riding bicycles to work, not because they are health conscious, or environmentally conscious, or because they particularly enjoy riding a bicycle in the rain.
They do it because they can't afford a car, or can't afford gas.
I've seen people spend hours cutting the grass in their yard with a scythe, because they can't afford a mower.
And in which country have you seen these things? We'll wait.
