Some fear that extending the workday will not produce more jobs because the resulting expansion of hours worked will reduce the capital-labor ratio. This would lower the marginal productivity of hours worked sufficiently to offset the positive effects of increasing the number of hours per worker.
一些人担心工作日增加所导致的资本对劳动比例降低将无法提供更多的工作岗位。它将会降低高效工作的每小时边际生产力，抵消掉增加每小时工人人数所带来的积极影响。
