Oh I agree, but let me rephrase this... my education to date has cost somewhere on the order of 180k (for 6 years of undergrad and grad education). Almost as much as a child, as much as a house. I am very fortunate that my parents and grandparents paid for undergrad, which leaves me with 60k in debt, for only 2 years of grad school.
I was really worried that I wasn't going to be able to finish my thesis, but I couldn't back out and be 60k in debt and no degree at the end. Ok, technically I could, but that would have been a terrible option. Likewise, technically a parent can do all sorts of things, most of them are not a good option.
All I mean by that analogy is that some people are willing to go crazy in debt for a top rate education. One that in all honesty probably won't pay for itself, or at the very least one that will not pay more than a comparable education at a less expensive school. To me it is worth it, because it was an amazing experience to learn from some really big names in my field.
So in that light I can understand that for some people having a child is such a priority to them that they would do anything to make that work, even go into debt. I think some parents do that with their eyes wide open, and many probably don't think about it that way first.
But speaking of kids, house, and education...
There was a girl in my program, and her husband was in the business school. Their student loans were monstrous, I can't put a number to it, I just remember thinking "that's a house", so it was something on the order of $250k. They moved back to CA, and bought a house for $750k... AND she is not working because she TTC. I can't even fathom it. Essentially a million dollars in debt, and only one person working, and potentially a little bundle of expensive on the way. He has a good job, but not a high dollar business job as he got his business degree specifically to market environmentally friendly alternatives.
I guess I should be happy that I only have one thing (education) that I'm willing to shell out disproportionate spending for.
