The Bottomline is it's evil to make a profit by a scheme of an "upline/downline" opportunity.
Many people can make a living by their own works 100% or by being in a commune or co-operative.
But evil companies teach others to have an "upline/downline" to vacuum a portion of the person below to render his/her works less than 100% due.
Another point is the lying and the twisting of words.
It's not a "team/company" if there is an unequal payment of a "upline/downline" involved.
An evil one could say the "upline/downline" exists to make it fair for the for the payment of training.
But does not a unworthy master learn from a worthy
In the end "uplines/downlines" will collapse in future with out a doubt. So don't join one.
Don't confuse an "upline/downline" to a heirarchy. A heirarchy gives the same but the other one does not.
