*Children now in their toddling years are going to be the ones wiping your bum when you are in your nursing home, diagnosing your Alzheimers, and paying into the pension pots so you can take out of them, if you are of working age. The parents who are staying home - often at financial cost to themselves - are the ones who are bearing the cost now.
If fewer people have children, this will be spread even more thinly and it will be even harder to find bum-wipers and Alzheimers-diagnosers and pension-payers. Children don't just benefit the parents of those children.*
See, parents who pat themselves on the back saying they are doing the rest of us a favor and we should be grateful are delusional.
First, there is no looming shortage of human beings. In fact with dire climate change and economic shifts, those descendents of yours will be lining up to change my adult diaper for a few coins and a biscuit at the rate we are going.
Second, I will have paid in the US social security system for more than 50 years by the time I retire, as well as disproportionately high income taxes relative to parents, property taxes on two properties (here prop tax pays for schools) for more than 50 years without ever enrolling a student in either district (which is fine, I believe in free public education) donated tens of thousands to charities that benefit women & children and otherwise more than done my share as an upstanding citizen without producing any liability for the health, welfare, education or public assistance systems here. Without ever taking tax credits or otherwise offsetting what I paid in. That future workers will then be doing their rightful share of providing cash flow for SS payouts is as it should be; they won't be doing me and other elders a favor. They will be doing their bare minimum duty. Furthermore, we can always import plenty of qualified workers to pay into these systems, no need to subsidize homegrown ones unless one is a xenophobe or bigot.
Third, parents aren't exactly doing the greatest job, at least here in the US, if you look at the high school dropout rate (35%), the teen pregnancy rate, piss-poor academic 'achievement' relative to other countries, the fact that very few Americans speak a second language, the levels of criminality among teens and 20-somethings, the massive backlog and gigantic public expense of the family courts systems and many other metrics. Do we of the village get to hold them accountable for these epic fails? No, we are supposed to accommodate, accommodate, accommodate and pay, pay, pay with no input into who breeds, when and how often.
Fourth, the human population is burgeoning at the expense of many other species that some of us find equally deserving to humans if not more so , from bees to elephants. Producing a western child is an environmental disaster.
Well, the village is getting a bit tired of this state of affairs. The era of special privileges for those producing "the next generation" is waning.
Do what you want to do to make your life fulfilling but don't expect to be thanked for it.
