> My other question that I've never found a good answer to, is with mechanization, how is it that "cheap" modern buildings are so expensive. Or were old, traditional buildings super expensive?

Old buildings were often expensive to their inhabitants because people were very poor. The cheap ones were largely torn down, because they fell apart because... they were cheap. Also, people largely lived in comparative squalor to today. Only about 50% of homes in America had an indoor flush toilet in 1926, and most of those were the urban north east. In 1926, the average home was <1k sqft (avg >2k in 2026). The modern idea of insulating a home wasn't around 100 years ago - houses were small, and cold, and you had to shit in a hut in the yard or in a bucket you threw out the window after.

Like cars, we've upgraded our standards of comfort and safety a lot. HVAC, electricity + internet networking, running water and bathrooms and water heaters, insulation, double paned windows, more and bigger appliances, safer standards for things like like staircase dimensions, increased fire/earthquake/hurricane/etc resistance, etc - there are a lot of things that just didn't get included in old homes.

Old houses were literally boxes made of wood, and now they're complex and mechanically rich in many subtle dimensions. Houses also have gotten bigger, so even as the price-per-sqft grows, so does the total size of the home.
