I hate when people are fooled by bullshit

Today I met a lot of creative people, it's always cool to meet creative people.
But I also met two losers who were going to live on pyramid selling. Wasn't it kind of me to tell them that they were fooled and probably had bought some marketing flummery. "But all companies are like pyramids", they told me, "the ones at the top earn much more than the ones at the bottom". Sure, but if you work in a normal company you know what terms you have, what salary you will get etc, you're normally not trying to convey your friends to join and pretend they will get cured or rich or something and most important of all, you don't need to pay a fortune for using the shit yourself.
I also told them there were investigations made my the National Food Administration that proved that what they had learned from some friends were just bullshit. Wasn't that kind of me? I didn't tell them in front of a lot of other people..
