Migration from 100 to 33 foot lot frontages has been ongoing for decades. The few "character" (old, original) homes remaining exist only where they were built in the middle of the original 100 foot lots.
1970: 1600-1800 sq ft, unfinished or partially finished basement, single carport, one car (occasionally two), very few recreational vehicles and trailers (the latter mainly those small collapsible tent trailers and some Bolers), rooftop-transported canoes and skiffs, once-every-few-years family vacation to Disneyland Anaheim.
2020: 2800+ sq ft, fully finished, two- or three-bay enclosed garage full of bicycles and seasonal recreational equipment and stacks of totes and boxes full of "stuff", at least two cars plus a project car or truck or motorized RV, large camper trailers and boat trailers, once-every-couple-of-years family vacation to resorts in Hawaii, Mexico, or Mediterranean.
Obviously the federal government has to step in and hand out money to these poor people trying to get by.
