The cost of a home has almost nothing to do with the materials. It's the developer that is trying to cut as much as possible, because this means he gets increased profit margins.

In this environment? Citation needed. Building materials of all sorts are difficult to source, often with long lead times, and are multiples of what they were a few years ago. Labor has gone up as well. Builders are lucky to get 20% margins.
This is plainly and patently false. Materials are (more or less) fully half of the cost of building. If you use nonstandard materials that goes up because you need specialized labor in addition.
