Also, people who need the services of childcare/homecare workers more than those of Human Resources personnel may say something is right when those services are more abundant and affordable.Something is wrong when childcare/homecare workers are valued that much less than Human Resources.
The fact that they are paid less does not mean that they are valued less. I pay less for water than I do for liquor, but I value the water more.
I realize those two terms don't necessarily equate, but in this case I would say the combination of lower pay, lack of training, and lack of benefits shows a lack of value from an industrial point of view. More detailed analysis here. Granted, this is finally starting to change but it's been a long time coming. If it were me I'd rather take comfort in the fact that the aide has been properly trained, has some sort of licensing, and is being properly compensated for their work in order to convince myself they are doing the best job they can do of taking care of x person. Many of the public programs that provide these services qualify for Medicare which makes it possible for lower-income families to afford them anyway.
I don't understand what "an industrial point of view" means. Pay for childcare/homecare workers comes from customers, people like us. If I needed to hire someone to care for a loved one, I would shop around and look for candidates that meet my expectations for experience, CPR training, or whatever else is important to me. If there are multiple options with similar qualifications, I would choose the less expensive one. I follow the same pattern when shopping for cell phone plans, shoes, movie tickets, and car washes. Do you do something different?
