Nader has lived his life in a way that tends to appeal to lefties, progressives, marxists etc. But even if you don't agree with his politics, his work has tended to be unbiased and honest. I remember he got pilloried for "Unsafe at Any Speed," his work on the GM Corvair's safety issues, and for his review of early 70s Ford Pintos and their gas tanks. He was pointing out some of the flaws of large-scale production when it starts to bend toward profit first, utility second.
Sort of like SIG USA lately, ya know?
