If you ever visited the killing fields in Cambodia, you'd never make a statement like that. A sub-optimal economic policy isn't even on the same measurement scale as the raw, senseless, brutal cruelty and violence of that regime.
Nothing I am saying diminishes that as an expression of profound evil. The question I've got though is why you're here minimizing the raw, senseless, brutal cruelty of 1990s neoliberal economic policies.
Just because you can't see pictures at the visitors center doesn't mean the misery is any less profound.
