My parents married when Mom was 34, Dad, 28. They are still living, happily married. Age is a factor if you plan on lots of children. Two of three children are living. My brother died after two days, reason unknown. The job at which my Dad worked 40 hour weeks provided enough money to enable Mom to quit her job to raise us. He bought a house and had excellent benefits, all on a high school diploma and three years of mechanical training from the military. The same job today requires a minimum of a Master's degree in mechanical engineering, computers expertise, and 8-10 years experience. The only jobs at the same firm for someone with high school and military training would be working part-time as a custodian, probably for a private cleaning company on a contract basis. IOW, in no way enabling a man to support a wife and family. Societal conditions have pushed the age of marriage way up for both men and women. It can no longer be said what are appropriate ages. My Mom hardly stayed waiting at home. At 34, she had worked her way up on a high school diploma to being in charge of billing at the local water utility. Her job is nowadays replaced by a computer! She did help my Dad to buy the house, outright, no mortgage.
I would emphasizes that any "ideals" must consider all the other factors, such as the time and place in which you live.
The post above was very interesting. It demonstrates what I have talked about many times -- how times have changed for the worse, and how young men have a harder time today (to get established) then they ever have before.
Another thing to not forget -- the Money Men who rejected Our Lord and use their media today to push society ever downward are the same ones who have debased our currency today, making it weaker than ever so that basically everyone is poor.
Inflation makes everything go up in price -- but wages are usually last to respond. That's why those with businesses have an easier time -- they raise their prices and that's that. But how long until they give their employees a raise? Much, much later, and not enough.
Moral of the story -- we have to be shrewd, clever, and wise as serpents if we want to get by in this world. Not just get by, but manage to get married, have a family, and raise one's children in such a way that they have a fighting chance of staying Catholic. It's quite a challenge.
