> I've seen videos of people tripping in their home and punching a hole in the drywall

Did that last year. Went to stretch and pressed my palms firmly on the wall and one side punched in. Apartment complex made me fix it too. You could also easily hear neighbors and whatever domestic dispute they were having that week. I live in a nice place now. Advertised as "luxury", but everything still seems cheaply built

I think a lot of this is that people don't know what to look for, so they buy based on appearance rather than quality.
