"The poorer is a family, the greater is the proportion of the total outgo which must be used for food... The proportion of the outgo used for food, other things being equal, is the best measure of the material standard of living of a population."

Of everything that man erects and builds in his urge for living nothing is in my eyes better and more valuable than bridges. They are more important than houses, more sacred than shrines. Belonging to everyone and being equal to everyone, useful, always built with a sense, on the spot where most human needs are crossing, they are more durable than other buildings and they do not serve for anything secret or bad.
