I'm interested in how one would prove that one way or another.
It seems to me that in the past there probably was lots of shoddy workmanship and just no-one paid attention to it.
But I have no proof of that.
Fortunately, there are millions of buildings that remain standing as evidence of what was done in the past. So at least there's that!
