makes sense to have kids when you can keep up with them

Yeah, I think there's a whole conversation that just isn't happening... some people are "too young", but then when you're a little older it can become different (or impossible to have kids at some point too, you can get too old)

There are a lot of declining fertility rates and I think this is part of that culture ("too young to have kids" ... to the point where people just don't have kids)

Even if there were a compromise - maybe not 16 but how about 20?

yeah, but I just expect people to keep moving the ages to older and older
