A rhetorical dog whistle is a coded message for select listeners, usually the politically correct. Euphemism is the breath that blows rhetorical dog whistles. A few examples suffice to make the point.(full story at americanthinker.com)
International economic dog whistles are perennials. Karl Marx and Maynard Keynes are still blowing from the grave. The socialist dog whistle calls for justice, but really signals an attack on success and wealth -- as if economic equality were not an affront to history and common sense anyway. And the Keynesian whistle would have government provide what the market will not; subsidies, bailouts, stimuli, and deficit spending. Where Marx and Keynes merge, the whistles might even hurt a dog's ears.
Another ugly signal lies under all that noise about justice, fairness, and equality. A majority of voters in Europe and America have come to believe that a shrinking class of employed or entrepreneurial can support a growing class of dependents, fiscal barnacles. Neither government nor voters believe that they need to separate wants from needs anymore. Yet the free lunch crowd has the vote; and may now have a quorum; enough votes to repeal common sense -- or mandate suicide.
