Expensive HDMI cables are for suckers, and this is why: An HDMI signal is purely digital. An analog signal like composite video is a radio wave that can be degraded and interfered with, but a digital signal is either a 1 or a 0, period. A digital signal works 100% or it doesn't work at all. Fancy gold-plated connectors do sort of make a difference with analog stuff, so people were used to the concept of premium cables when HDMI rolled around. Nobody was going to question it, so they made expensive fancy HDMI cables to take advantage of people's ignorance.
