Your logic is compelling but I think is not quite accurate as many other people have commented here. However, I do agree that due to the many challenges many people face there are many couples out there who have trouble coming to terms with reality.
It is not that these people are selfish or uncaring it is just the stress of living with the constant fires that they are putting out, mostly of a financial nature.
Young people in the Yeshivish world who want to live a kollel life without depriving themselves of life’s comforts will have stress unless their parents are wealthy.
Even working people have much financial with the unending tuition, bills, etc etc.
Solution?
Effective communication and common purpose.
And mutual respect.
Any missing element from this three legged stool and you are facing a pretty unhappy journey through life.
