Some people have likened Mormonism to MLM. I know where they're coming from, but I think Mormonism is worse than MLM. Far worse.
Let's look at it this way:
If you work seven days a week with Amway (or most other MLM businesses) there is a possibility that you might earn a decent income.
But if you work seven days a week at being a Mormon the only people who do well are the very small amount of people in the Mormon Church who are the the top of the Mormon pyramid.
So no matter how much time and money you give to the Mormon church, you will never earn a penny from all your efforts. And that, in my opinion, is worse than any MLM that is not 100% crooked.
