New homes are a bit of unique version of the "built to last" theme. Most of the individual components are some of the best we've ever had, while some of them are the worst. Modern windows are amazing. Modern insulation is amazing. Insulation is so good, you need less of it in appliances so you gain space inside fridges/ovens even though the unit itself is the same physical size. If you built the house out of something besides #2 pine, homes could be amazing. On top of that, you have nail guns where the builder doesn't even notice (or care) if the nail misses or not. People just don't care about the attention to detail during construction. It's not like they're building their own home.
Sounds like a "shortage of (quality) labor" problem. Industrial products are great, but craftsmanship is lacking because almost nobody can afford it.
