Those ones do more harm than good, imo, because they take away personal accountability by focusing on the system, as if to imply that all we need to do is select the right system, which has somehow eluded us for centuries. Any system works just fine with decent people and no system works with shitty people. There is no system that's capable of forcing decency, because of the whole, "where there's a will, there's a way" kind of thing. It's the will that we need to work on.
