successful ones with big cribs n rides are those on top..meaning thr was lots of opportunity for them when mlm was still young. ppl say its a scam bcuz u can hardly be successful as them nowadays with the current knowledge of ppl. 1month wont get u anywhere..as u will have to pay upfront to get to sell their 'products' and collect ' member fees'. and 14hours to get 1k? only if u have lines of ppl waiting to join u.

Here are what I consider the general pros and cons of MLM: -

Advantages:
1) you get to set your own working hours because you are your own boss
2) Very minimal startup costs compared to starting a franchise/brick and mortar business.
3) Established infrastructure/plan.
4) Regular motivation in form of seminars/cds/success stories (depends on the company anyway).
5) Presence of a sponsor/mentor to guide you throughout.

Disadvantages:
1) Certain companies may limit your creativity by putting some restrictions on advertising/marketing.
2) Though you are your own boss, you may have to periodically attend seminars/meetings, wear business attire even if you may not like it.
3) You may or may not like your sponsor's/company's overall attitude.
4) You may have to compete with your peers in your area/region.
5) You have to be an effective speaker.
6) Some may get intimidated (those with low self esteem) by attending seminars/meetings.
