To believe, however, that wage pressures will not intensify as the group of people who are not working, but who would like to, rapidly diminishes, strains credibility. The law of supply and demand has not been repealed. If labor demand continues to outpace sustainable increases in supply, the question is surely when, not whether, labor costs will escalate more rapidly.
There is a broad consensus that no explicit definition should be prescribed. It would in any case be virtually impossible to capture the diversity of procedures and their continuous development in a rigid definition. The focus should not be on generalised requirements, but on specific use cases.
