Why is it so? New houses have more than doubled in size since the 1950s while holding one less occupant on average. Houses have a lot more amenities than they used to have, like AC and a clothes dryer instead of a clothes line. We have torn down about a million SROs* since the 1950s and largely zoned out of existence the ability to build new Missing Middle housing. We are more car oriented than in the past and cars are typically the second largest expense in a household budget and they've gotten crazy expensive as well. Having said that, I will recommend the (possibly out of print) book How to survive without a salary by Charles Long in support of your crazy plan. ;) * https://en.m.wikipedia.org/wiki/Single_room_occupancy https://en.m.wikipedia.org/wiki/Single_room_occupancy
