Pierce Butler, Morehead v. New York ex rel. Tipaldo…
“ There is grim irony in speaking of the freedom of contract of those who, because of their economic necessities, give their service for less than is needful to keep body and soul together. But if this is freedom of contract no one has ever denied that it is freedom which may be restrained, notwithstanding the Fourteenth Amendment, by a statute passed in the public interest. ”
