The difficulties referred to principally concerned the Catholic's attitude to private property, the wage system, and moderate Socialism.
With regard to private property, Our Predecessor reaffirmed its origin in natural law, and enlarged upon its social aspect and the obligations of ownership.
As for the wage system, while rejecting the view that it is unjust of its very nature, he condemned the inhuman and unjust way in which is it so often implemented, and specified the terms and conditions to be observed if justice and equity are not to be violated.
In this connection, as Our Predecessor clearly points out, it is advisable in the present circumstances that the wage-contract be somewhat modified by applying to it elements taken from the contract of partnership, so that "wage-earners and other employees participate in the ownership or the management, or in some way share in the profits." 11Cf. ibid. p. 199.
