Hello,
Sadly these companies make money off selling BS. If only people would stop giving them their cash, they would stop in a heartbeat.
But in reality there is "one born every minute" has always been true and this will never stop.
Its not a bad thing. Only those who are extremely rich could afford such stuff. If we could get the rich to spend more, evonomy will be better. Even though these companies are selling snake oil stuff, they still need to employ people to work for them. So, the rich buy their stuff, these pple get jobs.
Since these products are so expensive, they won't get any money from the rest of us...
