Multi-level marketing can indeed work for folks. However, they need to enter into the deal with the notion that they will have to work just as hard at whatever MLM venture they do as they would at any other job (actually, people sucessful in MLM may work harder because its "their" business.

Mom and Dad should look at their retirement goals and how this would fit in. What do they want to earn monthly from Amway and what level of effort would this require?

Additionally, alot of people fail because they don't fully appreciate what is expected/required for success. You really need to be out selling beyond initial family and friends. Are Mom and Dad willing to do that?
