Monty's (From Xiph) lecture about digital signals on how 24-bit/192 KHz media has no audible differences when compared to 16-bit/44.1 KHz media can be applied to cables as well.
Until somebody that has golden ears (Please submit yourself as a subject as scientists are dying to study you) can prove in a double blind A/B test that there is a difference between cable A and cable B, then expensive cables merely exist to strip people with limited scientific knowledge of their hard earned money. This is assuming cable A is a Monoprice 14/16AWG cable and cable B is some ridiculous Nordost frey snake-oil cable.
Just because someone else can hear a difference, doesn't mean you can, so try the same double blind A/B test yourself.
There will always be a number of people with more money than sense and that's what these businessmen exploit, it's simply profitable business so why wouldn't they?
