Common sense tells us that constant violation of a law results in erosion of, and lack of respect for, at least that law (US Code, Title 8) if not law in general.
I suppose someone subscribing to `act' utilitarianism would say make (yet another) exception to this latest group of "Call us Mexicans!" lawbreakers. If that is granted then general `rule' utilitarianism would dictate/require, IMAO, that the lawmakers--Dims and Pubs--be compelled to clean up this mess since they have failed miserably in their roles as law enforcement officers.
Ya know....I can't think of a better reason for law-abiding Americans to start an underground system of avoiding taxes, even more than is done already!!!
