TheAtlantic did an extensive survey Senate offices, "How the Senate Exploits Unpaid Interns -- Barely a third of U.S. senators pay their interns -- and embarrassingly for Democrats, a party focused on workplace welfare, most of them are Republicans.":
Needless to say, there is a distinct contrast between the leaders -- many of whom are proud of their own previous internships -- who perform “public service” for pay, and the youth they ask to do the same for free. Second, and embarrassingly for Reid and the blue team, the vast majority of senators who do pay are Republicans.
Of those 35 senators, only 11 are Democrats -- meaning almost 80 percent of Dems require volunteer participation (not counting Bernie Sanders, an independent who caucuses with the Democrats). This is peculiar and troubling for a party that elsewhere signals its commitment to fair pay, equal representation, economic inequality, and workplace welfare. When it comes to interns in the Senate, it seems that traditional beliefs about labor and economic opportunity are suddenly switched. Despite frequently proposing and voting in favor of legislation that opens the workplace door to all Americans, Democrats ignore the same values when it comes to their interns. Reid's office did not respond to requests for comments...
half of senate Republicans have decided to pay interns, and should perhaps earn some rare positive reinforcement from labor activists.Editor's comment - We're not surprised. Republicans are just better people than Democrats. No rocket science involved. Just common sense.
