I believe "cruel and unusual" is obviously context dependent and intended to prohibit the government from applying punishments that are technically permissible under the law but which society considers completely unreasonable under the circumstances. The argument that fining a homeless person is not cruel because fining a rich person is not cruel and thus fines can not be cruel is absurd.
