Walker also thinks Koch knows exactly what he means by their "freedoms," and I think I know too. Between about 1900 and 1937, the US Supreme Court repeatedly struck down legislative provisions - state and federal - attempting economic reform. The most famous of these cases is Lochner v. New York, decided in 1905, which was precipitated by New York's attempt to prohibit employers from forcing bakers to work more than 66 hours per week because baking was a hazardous occupation in 1905. In addition to white lung, bakers in 1905 went repeatedly from extreme heat to extreme cold, and pneumonia and related respiratory illnesses were rampant. Unions were illegal in the United States, employers paid for no benefits, and employees could not afford them.
The Supreme Court struck down the law on the basis of a doctrine called "substantive due process," which it theorized embodied a bundle of irreducible "liberties," one of which was liberty of contract. The court venerated "the right of the individual to labor for such time as he may choose," a right that did not exist in the real world because of the disparity in bargaining power. Oliver Wendell Holmes dissented, and pulled the covers off the court's normally secret deliberations, by revealing that "[t]his case is decided upon an economic theory which a large part of the country does not entertain."
The doctrine was used by the court to prohibit government from interfering with even the most pernicious conditions under which children labored, from requiring safe work place conditions, from ameliorating sweat shops and, ultimately, to protect every reprehensible employer excess that our contemporary labor laws were enacted to prevent.
That is Koch's idea of freedom, and Scott Walker apparently agrees with him - he is "one of us!"
