What is going on in the service industry?

When I think of service industry, I think certainly not one-size-fits-all. I do not think that the human factor is a small and subordinated to the whole. I do not think service industry even slightly resembles production from the 80s in the last millennium. Am I wrong? 

Many in the service industry, from healthcare to ICT, are busy embracing principles that were seen as a solution for production from the distant past. A time of high volumes, few changes, thinking that there is infinite capacity, labor marginal factor. Why?
