Exxon Valdez was the most job creating oil tanker to ever sail. Think of the thousands of jobs that have been created to clean that up.
"creating jobs" is a placeholder for "economic activity" with the benefit of always making it appear positive.
It's a euphemism that's used when nothing more legitimate can be found.
In the business context it's insidious in yet another way. Deals and contracts that will make certain privileged people gobs of money is presented as "job creating" because people are needed to execute the deal or do the dirty work. In this case, the Wisconsin tax payer is paying $1,500,000 to foxconn for each job.
The focus is removed from the cost to society, who benefits the most, or the structure and merits of a particular event. They get papered over with the economic equivalent of rainbows and puppies: "job creators".
