The first remedy, or prevention, is to remove, by all means possible, that material cause of sedition whereof we spake, which is, want and poverty in the estate;[170] to which purpose serveth the opening and well-balancing of trade; the cherishing of manufactures; the banishing of idleness; the repressing of waste and excess by sumptuary laws;[171] the improvement and husbanding of the soil; the regulating of prices of things vendible; the moderating of taxes and tributes, and the like. Generally, it is to be foreseen that the population of a kingdom (especially if it be not mown down by wars) do not exceed the stock of the kingdom which should maintain them; neither is the population to be reckoned only by number; for a smaller number, that spend more and earn less, do wear out an estate sooner than a greater number that live lower and gather more. Therefore the multiplying of nobility and other degrees of quality, in an over-proportion to the common people, doth speedily bring a state to necessity; and so doth likewise an overgrown clergy, for they bring nothing to the stock;[172] and in like manner, when more are bred scholars than preferments can take off. It is likewise to be remembered, that, forasmuch as the increase of any estate must be upon the foreigner[173] (for whatsoever is somewhere gotten is somewhere lost), there be but three things which one nation selleth unto another; the commodity, as nature yieldeth it; the manufacture; and the vecture, or carriage; so that, if these three wheels go, wealth will flow as in a spring tide. And it cometh many times to pass, that, “materiam superabit opus,”[174] that the work and carriage is more worth than the material, and enricheth a state more; as is notably seen in the Low Countrymen, who have the best mines[175] above ground in the world. Above all things, good policy is to be used, that the treasure and moneys in a state be not gathered into few hands; for, otherwise, a state may have a great stock, and yet starve. And money is like muck,[176] not good except it be spread. This is done chiefly by suppressing, or, at the least, keeping a strait hand upon the devouring trades of usury, engrossing[177] great pasturages, and the like.
