A Treatment for Intergenerational Resentment

I recently saw a TV skit making fun of the baby boomer generation for ensuring that they had first access to vaccines since that generation currently holds a majority of total power and wealth.  I suppose over the course of human history, intergenerational resentment has often been a problem in society, but this got me thinking.

Modern culture seems idealize kicking kids out of the house as early as possible, comparing this to birds having to force their babies to leave the nest.  Yet housing, whether apartments, condominiums or single-family residences, is out of reach for people making an average income in many places.  This problem is even more acute for young people who almost always start out their careers with a below average income.  To some extent the situation is improved if the young people can be subsidized by their older, wealthier parents, for example providing funds for a down payment on a house.

Rather than every nuclear family in their own single family residence (SFR), I feel like the model of having a big house or duplex/triplex/quadriplex is a good way for a multigenerational family (including grandparents, aunts, uncles, cousins, grandchildren) to save money in aggregate, especially if there are common areas.  It also increases family propinquity which, I believe, will tie the family closer while still allowing privacy.

Having these dwellings serve as the basis of suburbs in a city rather than SFRs would be a way to increase density without (hopefully) making people feel more tightly packed.  Increased density is a way to make transportation more efficient.

If the wealthiest generation is the oldest, as is often the case, then allowing everyone to live in their property is a good way to share the value of wealth rather than overtly giving it away. This situation is ideal if ownership can be kept in the family over the course of many generations.

For all these reasons, I believe a city full of multigenerational, extended families living in triplexes and quadriplexes would be a much more efficient and happier place to live.
