Sir Hubert Douglas Henderson, Supply and Demand
“ The business which finds it worth while to offer the highest rent or the highest price for any piece of land will, as a rule, be able to command its use. And, with this as the governing principle, an apportionment is secured between shops, offices, factories, agriculture, between the immense variety of different employments covered by each of these broad headings; not a rigid unvarying apportionment, but one which constantly changes as economic circumstances change, and as the margin of transference between different occupations moves hither and thither. ”
