I'm not going to read 7 pages of the same opinions and partial excuses...
Anywhere in all those replies did ANYONE bother asking where this $8/hour employe is going to get startup capital? Let alone, enough money to float the business for the cycles that it will take to become profitable. No bank will ever give that person a line of credit, or if they did, the hourly employee would have to put up his/her equity in their home, or whatever other meager valuables they have, all in exchange for bare minimum or insufficient funds, at a very high cost of funds (interest rate).
It's just not financially possible. That person *could* find a money investor/silent partner, but those folks are loathe to turn over control to a non-stakeholder.
Sorry folks, but there really is something to the old adage that it takes money to make money. It also takes a decent education, both in school and in business, to achieve success.
The simple, definite answer to the OP's question is that they do not because:
1) They cannot (lack of opportunity).
2) They're afraid of change
3) They are unaware of opportunities
4) They're dumb or otherwise handicapped (from a success standpoint)
Ever seen a street kid who hustles (drugs, fenced goods, etc)? It most CERTAINLY IS NOT a question of motivation. There are kids out there who bust their rears selling things we wish they wouldn't sell simply because that's the main and easiest (though riskiest, which brings in to question the fear angle) opportunity available to them.
