What % of that 99% of America do you think are capable of starting and sustaining a business?
Assuming that all of them are smart enough and have skills to do so.. who do they sell stuff to, if 99% of everyone is broke? Where do they get initial capital?
75-90% of working adults would be able to start a business (remember business, not a startup. Cutting peoples lawns, fixing toilets, cleaning windows, picking kids up from school, etc could be the basis of a business)
They could sell to the others who where starting businesses, and to the 1% who would have to buy what they want from the 99%. It would also be the 1% whom they get their initial investment from, given that they would want their monies to grow.
