My last house was built in 1964 and the wood would be considered extravagant by today's standards. It was no fancy house, either, just a garden variety ranch. But it had decent (as I said, not fancy) oak hardwood throughout. Actual 2x4s that weigh 2x as much as fir studs today. Old-growth cedar siding. It was built in an era where it was no big deal to use good wood for everything.
