I agree that this stuff promotes copying, but at $79.00 its easy to see why these folks are having success at doing it!
Unfortunately a large segment of society has gotten to a point where they feel they 'deserve' to have the same things as people who make more money do, this lead to a massive increase in knock-off's being produced, which has even lead to a reduction in quality of some of the upper end products (due to alot of people's apparent widespread willingness to accept inferior products). Something else that goes hand in hand with people feeling they 'deserve' to have the same things as other people is refered to as 'consumerism'. Consumerism is the 'feeling' of personal happiness thru the consumption and purchase of material possessions - this 'feeling' is from the various 'feel-good' chemicals released in the brain (Oxcytocin, Serotonin, Dopamine, etc). Those chemicals are naturally released in the brain when your healthy, happy, loved, excited, etc. - but unfortunately they are also deceptively released in some other situations ('deceptive' because the actions themselves are often times unhealthy and/or dangerous and are actually being used as band-aids to cover up other problems). Drug use, drinking, eating junk food / excessive eating, fighting, promiscuity, consumerism, etc are all examples of band-aids being used to try and make up for 'feel-good' chemicals not naturally being released in a persons brain in their every day life.
Luckily for the manufacturers of the knock-off junk (alot of which is coming out of China) the combination of people feeling they 'deserve' to have everything and 'consumerism' has resulted in a thriving knock-off market in the USA. Many people have become so accepting of buying inferior products (because they got that 'feel-good' rush from getting such 'a good deal') that they don't care if they have to replace it when it fails prematurely (because they get another 'rush' when they buy again and get another 'great deal').
It's a sad vicous cycle, but an unfortunate reality today!
