Those who think that such matters find their own level, and regulate themselves, may be right in the long run, for so they indeed do. But how? When poverty and want came, no doubt the consumption of flesh-meat would be diminished; when the country had no means of supplying itself as it did when it was rich, famine would play its part in becoming one of the regulators; but, before this regulation could be effected, the evil we wish to prevent would have taken place. The country would be depopulated and ruined. We must, therefore, in trying to avert the decline of a nation, not set any thing down for the counteracting and adjusting power, which is known sometimes to interfere so very advantageously in the affairs of men. Though it is true that it does interfere, it is in all cases of this sort too late, it is an effect of the cause which we wish to avoid; we can only look to it here for stopping the career in process of time, but, never for preventing it. We know that the extravagance of an individual impairs his fortune, and, that the diminution of means will, at length, counteract the extravagance; but, then it will do so when it is too late, and after he is ruined. Wastefulness may be stopped, but it cannot possibly stop itself, as the diminution of means is the cause of the extravagance ceasing, and itself is an effect of the prior existence of the extravagance. Regarding men merely then as producing and consuming, (the proportion between which regulates the wealth of a nation,) we find that, in their own persons, there is a rooted tendency to bring on the decline. But we shall farther find that not only do people in wealthy and luxurious nations produce less and consume more than in nations less advanced, but they increase the number of unproductive labourers, all of whom consume without producing. They also main- [end of page #146] tain animals who consume, but do nothing towards production. {120} No country, in which the people live much upon animal food, can be well peopled. Two hundred persons to a square mile of country is nearly the highest population of any nation in Europe, that is, as near as may be, three acres and a quarter to each person; but, on an average, even in France, there are more than four acres to each. Supposing that one-half of the land is cultivated, then that gives about two acres to each person. Supposing, again, that one-third of this is consumed by horses or other animals who labour; or, supposing that they do not serve for the food of man, then there will be nearly about one acre and a quarter for the maintenance of each person. It will, however, only require half an acre to one person, if they all lived on field vegetables; {121} and, if they all lived on fresh meat, it would require four acres; the natural conclusion is, that one-fourth live on animal food, and the other three-fourths on vegetables, or what is the same thing, that the proportions of the two sorts of food are as one to three.
