People have a hard time admitting in retrospect they wished they didn't have kids because of biological bonding. My life would have INFINITELY less responsibilities and much more money had I not had a child. Are those things worth trading in retrospect? I don't know the answer to that because the toothpaste is already out of the tube. I'm currently middle aged, but if given the opportunity to go back in time and choose to either have kids or not, I probably would have chosen not. It's not because I don't love my kid to the moon and back, but it's a huge responsibility not many people can deal with. It's worth noting this is mindset is exacerbated by being divorced from my child's other parent, and it forces me to have to interact with a formerly abusive partner periodically.
