It's funny when you hear about a specific business whether its a MLM or brick & Mortar store how everyone immediately checks Google.  First, Google does not care if what you say is true.  In fact, with zero fact checking, it's merely an opinion, not a review. Doing due diligence means doing it correctly.

Businesses can have all the integrity they want, it's the people in the field that will make or break them as rogue representatives or conscientious ones.

If you were a corporation that had franchises and one did not want to follow your policies & procedures or pretended to, they would not be in business very long.  When they do go out of business, it's the core brand that gets the blame.  Know that the next time you "hear" or "read" something about a company.  99% of the time, it was a rogue franchisee who thought they could do it better or knew more than the corporation.

Corporations have integrity, people don't always

If you can not make more than your CEO or the more money you make for the company goes to the CEO's new summer home #3, then you are in a pyramid by definition.  You will only make those above you fat.

Home Based Businesses are not designed to replace your full time job initially.  They are designed to give you supplemental income that can build to replace your full time job if you so desire and do the work for it.

But working 40 years to retire and get 40% of what didn't pay your bills in the first place is the truest form of insanity there is.
