To have children or not is a deeply personal choice ☺️
And also personal is the search for meaning in ones own existence. While searching we create: life, art, relationships, meaning. Memes. I think life becomes a burden, when external factors keep you from creating the meaning that you care for.
But speaking as a historian: we put a lot of presure on parents over the last decades. And the same presure on kids. It is relateable that having children or just excisting has become so... whats a fitting english word?.. not desireable?
You know, believing that only leads to depression, i figure out. A depression, where nothing starts to matter and nothing could bring joy, so the only choice one can really have is... not participating in life anymore.
And it reduce parents to selfish beings and can lead to not seeing them as people (who mostly have feelings for their own kids).
