None of that is "inefficiency." In fact, since it's so successful at making people buy things, as you seem to state, given no proof, then you're just proving the parent's point, that it's very efficient. An inefficient process wouldn't be this good at making people buy stuff. I think you're confusing efficiency with value judgments of good and bad.

A slaughterhouse for example is very efficient at processing animals from living beings into mass produced meat, however you want to feel about the ethics of that.
