Here are a couple of excellent sources of information about the real goals of the Koch brothers and their partners in the GOP, their institutes (American Enterprise, American Heritage, Cato, Federalist Society, and myriad others)…
While their language is that of “freedom” and “liberty,” their interpretation of those words is “Freedom for the ultra wealthy to do what they want without any interference from government whatsoever. Whether wage slavery, environmental destruction, monopolies … ”
Their radical beliefs are based on property rights (of the wealthy) being sacrosanct, in fact, more sacred than human life or rights. While their words imply “freedom and liberty” for everyone, in practice, their policies only benefit the ultra-wealthy.
This is no accident. The language is chosen specifically to deceive ordinary people.
