Yea, there are pros and cons to bigger and smaller homes. It’s just that the marketing of the Tiny House “Movement” and the constant pushing for us to be happy with small apartments instead of houses reminds me of Huxley. “Alpha children wear grey. They work much harder than we do, because they're so frightfully clever. I'm awfully glad I'm a Beta, because I don't work so hard.”
I don't see that kind of sentiment in people I know who like tiny houses. If anything it's the opposite: they work a lot harder to save up to buy a tiny house (it's like 200k) vs continuing to rent. It's also harder to go against the grain than it is to flow with what society tells you to do.
