It's merely one factor among many, I'm sure, but don't the results, ever decreasing fertility, speak for themselves?Why would you attribute decreasing fertility, something that affects every western nation on the planet, as something to do with US health care? It even affects Russia, China, Japan, literally every "modernized" nation.
People have had condoms and other methods to prevent pregnancy, but no one ever cared about the cost of kids before the last few decades. This is merely an excuse, for what is really happening...
Lack of fertility due to some environmental factor.
If it was cultural, Japan and China ... nations most divergent from US and Western cultures, would not be affected the same way. It doesn't matter about access to the pill, or other measures, nations with or without the pill in wide use have low birth rates. Nations strong on women's rights, and more "traditional" views on women, also have reduced fertility and births.
It's not cultural. It's not choice. It's not cost. It's not conscious.
There is, quite literally, something affecting a drive to procreate, which is entirely different from the drive to have sex.
Given that it's not cultural, and that it's not access to contraceptives, one has to wonder what it could be. Microplastics? Electricity? The types of food consumed, eg preservatives in modern foods seen in all the above countries?
There can be guesses, but no one is even doing any substantial research into this. Meanwhile, the planet's population is set to halve within 30 years. And if this trend continues, if fertility / birth rates continue to decline as they have been, we will likely be down to 500M people worldwide before the 2100s.
That is an immensely alarming trend, which leads to human extinction by the 2200s, due to "whatever it is" completely blocking all attempts to have offspring.
This trend also doesn't take into account a global plague, or re-emergence of world war, or devastating health issues due to global warming. Should that happen, with "loads of our current, younger offspring" killed in war, or by plague, the trend is astonishingly scary and disturbing.
Sorry to be a bit excessive in my reply, but the whole fertility thing is greatly disturbing to me.
