Euphemistic term for a wealthy or rich person first proposed by Republican politicians in mid-2011.The term is meant to justify why the wealthy are given special legal and economic advantages and why the rich are taxed less than other people in the United States even though they can afford it more.In Republican/Tea Party political theory, "Job Creators" are wealthy because they are industrious, virtuous, hard working people and can use their vast wealth to create jobs by hiring people to work for them. The idea that this euphemism is trying to convey is that taxing these people would hurt the economy because then their money would be going to the government (which is always evil in this political ideology) which will only waste tax money on things like social services.
