“Economic freedom” per the Kochs and their network of libertarian think tanks means your freedom as an industrialist to bring government soldiers in to help you forcibly suppress worker strikes. It means your freedom to dump whatever you want into the local river, without pesky interference from the EPA. It means your freedom to create propaganda venues masquerading as news with no accountability. It means the freedom to force all dispute resolution out of a publicly accountable court system into private arbitration. It means your freedom to funnel money secretly to university-affiliated “scientists” to publish bogus studies casting doubt on climate change or the harmful effects of particular products. It means the freedom to secretly donate unlimited amounts of money to political campaigns, and make sure the law supports your hiring politicians and government officials at high salaries after they leave public office. Etc.
The “robber barons” are their heroes and their dream is a return to the Gilded Age.
Labeling this “freedom” is a pretty cute bit of rhetorical gymnastics.
