The Republicans have substituted "job creator" for the word "rich" in discussions of tax policy. It is absolute standard practice for them to object to taxing people who have money by saying that this will reduce job creation.
Since this claim has become so central in policy debates, Morning Edition decided to do what any reasonable news organization might do: see if it is true. Morning Edition called the Republican party and asked to be put in contact with some tax burdened job creators. They were unable to provide anyone for NPR to interview. NPR then contacted several of the business lobbies who have been complaining that higher taxes would impede job growth. These organizations were also unable to find any job creators who would speak to NPR.
NPR then put in a request to talk to job creators on Facebook. It got several responses from small business owners. The ones featured on its segment said that the personal tax rate would affect their disposable income but would have no effect on their hiring. This is pretty much what economic theory would predict.
