The rush to start a new biz

There have been many direct sales companies that have failed lately and then the DAY AFTER this happens, consultants with the prior company think "OhhhhI CAN open my own biz" and they get a domain name, forward it to a freewebs site and they think they're in biz!!!!

do they take into consideration:
Inventory
Packaging
Labeling
Shipping
Customer Service
Toll free phone
laser printer to print 'professionally'
If they're goin to have consultants, the plan for them
ROI (return on investment)
Schedules/Work Hours
Return Policy/Refund Policy
Professional looking web site with real domain name, real email address
yadda yadda blah blah blah ya know.....

and then a month or maybe a few months down the road they wonder why they flopped as well

just thinking out loud here...
