Earlier quoted context omitted.
There is a difference between wedding and marriage. A wedding paperwork is not too expensive, but a marriage has truly become unaffordable.
How has marriage become unaffordable? In what way? I'm really asking. Seems to me two people with two incomes living in a 1 bedroom apartment is cheaper than one. Nearly everything is cheaper when you're married: Insurance, taxes, meals, utilities. What's less expensive as a single?
Having so many people with no lived experience means lower cultural forces behind asking them to participate in an expensive party, even though marriage is so good for raising children (which used to be the purpose of marriage).
