I have definitely made a 180 or maybe even a 360 with these issues throughout the course of my life.
When i was really young i always thought i wanted a lot of kids. The grandparents on my dad's side had 9 kids, therefore i had loads of cousins as well and it felt great to always have someone to play with.
Then in my later teenage years/young adult i somehow got sucked into the egotrip where i considered kids a burden i probably did not want. It's my life and i should be able to live it the way i want. It was also during this time that i met most of the friends that i still have. I think a bit more than half of them don't have kids.
It was not until in my early 30s where i had held a steady relationship for about 4 years that kids started appealing to me again. But the general concensus amongst a lot of my friends was still that the "happiest" people were supposedly the people without kids and the few that did have kids often became the victim of the occasional ridicule and "overpopulation" and "bad for the environment" remarks.
I decided to ignore it and had 2 daughters anyway. Then, for the first time i heard somebody call out the term "civilization collapse". I started looking into it and i felt pretty stupid that i never understood population demographics and that upside down population pyramids are probably the worst thing you can do to your country.
Looking back at it now i wish things could be different but i only met my wife in my late 20s and when we started living together it was actually not super comfortable to make ends meet. Even as a sortware developer, a job that pays above average, i still could not have afforded the simple house that we still live in today. I needed the second income just to live together. My dad was an agriculture machinery mechanic, made probably not a quarter of what i make, but my mom could afford to stay at home and take care of me and my sister and we lived in a house more than double the size of what me and my girlfriend could afford combining our incomes.
There are probably a lot of things contributing to this but the state of affairs over the last 3 decades has been horrible. I can't believe that with all the progress we made as a society we have regressed so much in basic, fundamental needs in our society where people must slave away jn the fiat mines and stop having kids.
Sorry for the incoherent ramblings. These things just get to me like nothing else.
