The further away a scholarly opinion is from direct observation and the more abstract and ‘theoretical’ it is, the more defenseless it becomes agains… - Gunnar Myrdal

Looking backward on a period which is finished, we are looking at actually realized returns, costs, etc., as those items are registered in the bookkeeping of business. In such an ex post calculation there is, as we will show later, an exact balance between the invested waiting and the value of gross investment [Phil: he appears to mean savings and investment]. Looking forward there is no such balance except under certain conditions which remain to be ascertained. In the ex ante calculus it is a question not of realized results but of anticipations, calculations, and plans driving the dynamic process forward. Had this distinction been kept in mind, much confusion about “saving and investment” would have been avoided. There is in fact no contradiction at all between the statement of an exact bookkeeping balance ex post and the obvious inference that in a situation in which saving is increasing without a corresponding increase in investment, or perhaps with an adverse movement in investment, there must be a tendency ex ante to disparity.

The breakdown of discrimination in one part of the labor market facilitates a similar change in all other parts of it. The vicious circle can be reversed.

During the ’thirties the danger of being a marginal worker became increased by social legislation intended to improve conditions on the labor market. The dilemma, as viewed from the Negro angle is this: on the one hand, Negroes constitute a disproportionately large number of the workers in the nation who work under imperfect safety rules, in unclean and unhealthy shops, for long hours, and for sweatshop wages; on the other hand, it has largely been the availability of such jobs which has given Negroes any employment at all. As exploitative working conditions are gradually being abolished, this, of course, must benefit Negro workers most, as they have been exploited most—but only if they are allowed to keep their employment. But it has mainly been their willingness to accept low labor standards which has been their protection. When government steps in to regulate labor conditions and to enforce minimum standards, it takes away nearly all that is left of the old labor monopoly in the “Negro jobs.”
As low wages and sub-standard labor conditions are most prevalent in the South, this danger is mainly restricted to Negro labor in that region. When the jobs are made better, the employer becomes less eager to hire Negroes, and white workers become more eager to take the jobs from the Negroes.
