These assumptions seem to have some big holes.  Clinton's economic policies seek to pick up in large part where Obama is leaving off, and he created over 10M (that's MILLION) jobs - about 10x as many as his predecessor.  Bill created 22M using similar "building" and "strengthening" language.  Clinton also has presented plans on how to support small businesses through both increased access to financing and simplifying regulatory processes.  So while we don't know exactly what will happen in terms of future job markets, this assumption of a shrinking market doesn't have much by way of facts to support it.
