You’re unfortunately vastly overrating the world before Ikea. I have the furniture passed down from the 70s and 80s and it’s all falling apart and made from plywood.

You have to go back to the 30s and earlier before you get furniture that will stand up like that, and making that furniture new today would cost more than almost anyone could afford.

And the only 30's - 60's furniture that survives will be mostly solid cabinets; they are neither in style (if you care) anymore, but more importantly they're no longer practical, as they were built for different lifestyles and - habits. Writing desks are cute in theory but nobody sits down to write letters anymore.

You are correct, I used Ikea as a generic name for cheap plywood stuff. But there was still strong furniture being built in that era, it didn't all stop in the 1930s, if anything, because a portion of the population even in the global north had not converted to a "modern" post-WWII lifestyle as we see in the movies.
