I love that you wrote an article about this! I learned about this recently. and I love that women are taking charge and running their own businesses and such. I live in a state Utah, Where our marriage age is significantly lower. Everyone seems so old fashioned here and we are pushed into marriage at young ages, Well mostly the people who are Mormon.
I have done my best to ignore that, I feel like I can somewhat relate to these "leftover" women ALREADY, at just the age of 23, Because I have chosen to start my own business and focus on traveling and my own development instead of childbearing and getting married. It's nice to see that women are doing what they WANT rather than being stuck in traditional roles.
I dunno. Caution. See my reply to @sweetsssj.
Perhaps it would best to marry while both of you are still working towards upper middle class. But then if you have children, you may inhibit your earning power (not necessarily, but likely).
It seems to be a tradeoff. I'd think carefully about that.
