Solidifying a bond with your significant other is a good thing, but I don't see how having kids would do that. I would rather allocate the time/resources I would have spent on kids on my significant other.
Kids are people too, mate. It's not like they are always these little devils running around; if you had one right now, they'd become an adult 30 years later.
And, since you mention it, kids can be quite the opposite of "resource hogs". We often tie this designation to people; the more of us, the worse off we are! When, in actuality, people can pro-create resources. They can work for a living, create sustainable sources of energy, and not get tied a fury of consuming at a dangerous rate.
If you'd rather spend time and resources on your lady friend to make her happy, you may be looking at the whole thing in a wrong way. Maybe she doesn't need a bunch of resources to be happy. Women want children, it's part of their DNA. If a species didn't have an urge to create more of its own, then the species would die out.
Also, do you think having children is a good thing for YOU (not society or the human species), and if so, why?
I know it's a part of AS to have difficulty recognizing emotion (my brother has it), so this is going to be tough to explain. Love, for all intents and purposes, is the great equalizer. Having children isn't all about sucking up as much from them to benefit yourself. They are
people, not some weird alien species that has nothing to do with you.
There comes a point in time where people need to stop worrying so much about themselves, and focus on spreading well-being to other people is needed. Imagine; you get up to the point where you are amazing with women, and have not a problem in your life. What next? Continue amassing useless items, or help to sustain the future for others? This world doesn't operate around trying to get to the maximum level of happiness. It isn't a scale. Happiness is a state; it is very difficult to exponentially increase that state. It gradually increases, as worries and necessities are taken care of, such as getting a sustainable job, being amazing with women and people, etc; but it won't increase if you just get more and more resources. Children enter as a way to spread that love and happiness. To create another human being which is loved, happy, and therefore can also translate joy into your own life.
