my $.02:
Were I in your shoes, I would attempt to get my daughter to follow the path of children first and doing so as a priority. Career? Following up on what you went to school for? Secondary. And not by a little bit.
Put it like this: why does one go to school? If it was to make $, then the raison d'etre to make more money than what you need for subsistence is to have a family. All else is hedonism. Looking at in the strictest sense, of course. So, congrats, your daughter got to the point where she's not only good to go on forming a family, but has options about whether to continue with her good career plus her husband's, or to go a different route that is also likely to lead to a good outcome.
Now, either one of those options might not be debt free millionaire at 30, but let's be honest: that's not what 99.9% of people are capable of accomplishing. Especially outside of the fields of finance, tech, or legal industries.
As an example, consider Airline pilots. In that field, you're (typically) barely getting out of the pissant regional carrier jobs by the time you're 30. And that's if you went super fast and knew that's what you wanted to do when you were 18 and didn't have any setbacks along the way and even got a little lucky here and there. But would you say that's a bad career to have even with the caveat that it takes more than a decade to get going? After a few more years and some more seniority, you're easily up into the $200-350K/yr (or more if you can go corporate!) wage bracket.
I'd say that's a pretty good life path even though you're not a 30yr old millionaire.
