How did family structure of this world go from Macro-family to Micro-family?

Probably cause with macro family, just too many people.

Everyone having to pitch in to change the sheets every time grandpa wets the bed again.
Uncle Bocefus coming to Thanksgiving to discuss his questionable political views.
Aunt Helga wanting to preach the gospel.

It just is too much hassle and not like those shows where families care about each other instead of trying to k*ll each other.

As in the size of the family? Probably due to cost of living over the decades, people pursuing their careers more and people on average having kids later.

The necessity for two income households started the downfall. It began the downfall of society also.

they outlawed polygamy... 🤔

Shrink ray. Its 2025 we got lazer now.
