Strikes are not necessarily connected with violence to either persons or property. Violence is provided for by the criminal law. Taking strikes by themselves, therefore, it may be believed that they are not great evils; they are costly, but they test the market. Supply and demand does not mean that the social forces will operate of themselves; the law, as laid down, assumes that every party will struggle to the utmost for its interests--if it does not do so, it will lose its interests. Buyers and sellers, borrowers and lenders, landlords and tenants, employers and employees, and all other parties to contracts, must be expected to develop their interests fully in the competition and struggle of life. It is for the health of the industrial organization that they should do so. The other social interests are in the constant habit of testing the market, in order to get all they can out of it. A strike, rationally begun and rationally conducted, only does the same thing for the wage-earning interest. The facts stare us plainly in the face, if we will only look at them, that the wages of the employees and the price of the products have nothing to do with each other; that the wages have nothing to do with the profits of the employer; that they have nothing to do with the cost of living or with the prosperity of the business. They are really governed by the supply and demand of labor, as every strike shows us, and by nothing else. Turning to the moral relations of the subject, we are constantly exhorted to do something to improve the relations of employer and employee. I submit that the relation in life which has the least bad feeling or personal bitterness in it is the pure business relation, the relation of contract, because it is a relation of bargain and consent and equivalence. Where is there so much dissension and bitterness as in family matters, where people try to act by sentiment and affection? The way to improve the relation of employer and employee is not to get sentiment into it, but to get sentiment out of it. We are told that classes are becoming more separated, and that the poor are learning to hate the rich, although there was a time when no class hatreds existed. I have sought diligently in history for the time when no class hatreds existed between rich and poor. I cannot find any such period, and I make bold to say that no one can point to it.
