Call me a curmudgeonly 36 year old who was married at age 22 and still happily married, but marriage as a trophy is backwards. Marriage means going through life together, for better or worse, not as a capstone to an in-progress adult life.
I would like nothing more than to get married early, but between two cross country moves in the last 4 years and potentially more in the future, unless my partner wasn't working or tied down, that seems very unlikely to happen. My parents also got married early, but could transition from single to dual income at the time, something harder to do nowadays.
Waiting to marry until you are stable seems like the smart thing to do given that traditional "man works, woman takes care of the house" isn't the way it works anymore.
I don't have a problem with people entering into somewhat codependent domestic relationships, that can be great if it's your thing and you find the right person. I just wish it wasn't held up as the social norm that everyone should aspire to. I don't think it's the right thing for the large majority of people.
But that's just my old-fashioned opinion.
