Here's a really quick analysis of This House Has People in It and the surrounding ARG:

The house is American ideology. Here are some of the main signs of this.

First, a vacation is planned for Orlando, Florida. Tom has the idea to go to South Africa instead, but Subject 1 protests that Africa has too many terrorists. This reflects America's xenophobia and ignorance about the rest of the world, as well as a paranoia over "terrorism".

In another situation, Subject 2 complains that a Chinese state-owned company is building a railway in America. This alludes to America's declining position in the world, and perhaps the crumbling infrastructure, as well as debt to foreign countries. Also note that the house is perpetually under construction with a live-in handy man, and many parts of the house are in disarray.

In the main 11-minute clip where Miranda goes through the floor, Subject 2 responds by thinking it's a test of their family bond. This could be referring to how a national crises will only strengthen senses of American pride, rather than cause us to question the national ideology.

Subject 2 also leads the family in a national-anthem-sounding song, and they all salute each other. This parallels America's nationalism. Notice how robotic these actions all are, as if to say that belief in American exceptionalsm is so normalized it's routine and automatic. People in the room don't even seem to notice Tom's boisterous, desperate sounding song about the flag.

Finally, Alan (as they Clayground host), says on his website that "capitalism doesn't work". Not much symbolism here, an on-the-nose hint about what the program is all about.

So in summary, the crumbling household is like America's crumbling infrastructure and democracy, which the family responds to with heightened, robotic patriotism. The insanity in the house mirror's the cognitive dissonance in America and the West as we champion a system that is constant crises, and while other countries excel beyond us.

The fact that the family's every meal seems to be pizza, and the son's favourite cartoon character lives on garbage, are also likely criticisms of American "fast" food consumer culture. The use of surveillance cameras also comments the U.S. surveillance state as revealed by Edward Snowden. There's much more symbolism here too, and maybe I'll go into it later.
