This is like saying a year of attending a trade school to become a plumber is equivalent to being a first grade teacher for a year.
1 year of experience + 1 year of experience is already more years of experience than 1 year of experience + 1 year of parenting. And it isn't too rare that it becomes 3-5 years of professional experience being more valuable to a company than 1 year of experience + the last 2-4 years of parenting when a parent tries to re-enter the work force.
You either have an impressive resume beforehand or accept that you traded career advancement for having children. Children are a choice and it isn't fair to people who chose not to have kids to further their careers to be brought down to "fair ground" by people who chose to have kids instead of furthering their careers.
if you're in a position where you can afford to shoulder the financial burden of having children, that's great and I wish you the best. if not, don't expect the small sliver of childfree folks to make up the difference for you. if we actually get to the point where society can't replace itself, maybe we can talk again.
It's exactly as rigorous as your argument. We've both submitted opinions to be considered. I'm not expecting more rigor nor inclined to offer more because I think we've both put out enough worth considering. But if you want to bring more rigor I'll read it.
When this is this is the case let me know. All I see is system pumping out special snowflakes that only know how to bitch and complain and scream at the slightest amount of discomfort or offense.
