I don’t disagree, I just don’t think “living in the same house for decades” qualifies as a clear signal of living simply. It could just as easily be a front or compulsive frugality. Or a really nice house to begin with. For instance, there’s no way my family would fit in the first house my wife and I bought. And we couldn’t have afforded our current house back then, either. It’s also worth noting that 60+ years ago was a very different house-buying experience. So I don’t think there’s much to learn from the fact that Warren Buffett bought a house back then and still lives in it, other than that it worked out for him and he’s not flaunting his wealth for whatever reason makes sense to him.
