Not having kids seems to be the first item in the list for that particular plan, so having a son disqualifies you!
Not to say that's a great plan. Having a life without kids wouldn't be a satisfying life for most people, and so if its a choice between kids and wealth, then most would choose kids.
I do think having kids early probably makes it much, much harder to become wealthy. My friends who had kids in their early 20's are generally poorer than my friends who waited until their 30's. I think a more realistic plan would be something that includes children, but waiting until you've had time to get some type of career started.
