Exactly @YesImawitch . Women who are not SAHMs and never want to be, but are perpetually in SAHM threads for decades, really do have to ask why. Especially if your kids are adults! It doesn't even matter what you're saying - why would you care enough to even engage? Who cares who may want appreciation, from whom, where and when? How does it affect you? Why does it even matter to you at all?
I mean, I work but it's obvious to me that SAHMs are undervalued in many ways. Children are a fact of life and someone needs to care for them. SAHPs (including dads if they SAH, or grandparents who may be with grandchildren) are doing the unpaid 'invisible' work that enables the paid 'visible' work of others to happen. If SAHPs are not with their kids day to day - it still has to be someone (nearly always women) who are chronically underpaid for the level of responsibility they have. They literally have other people's children's lives in their hands. What matters more than that?
In fact all caring work is undervalued - children, elderly, disabled, social care, nursing - the whole spectrum.
I have no issue whatsoever in saying that the job a SAHM does is more valuable than the work I do now, and the work of probably the majority of people. And the work that a childminder in a nursery does is far more important than probably the vast majority of jobs, when you consider risks and worst case scenarios. I think this is obvious. It takes nothing away from my parenting to declare that people in charge of our children, SAHP, grandparent or childminder, should be highly respected in society for their role. Not everyone can do it. Not everyone has the patience or the resilience. Those who can do it and should be applauded, frankly.
