I agree with his point. It used to be that the government realized it needed an amendment in order to do things the Constitution didn't give it power to do. For example, long ago they needed an amdendment to prohibit alcohol, yet now they do the same thing with drugs through regular laws.
Now this idea of circumventing the Constitution is entrenched. Formerly the idea was used for the government to gain powers not given it by the Constitution (as above), but in the last few decades they've gotten bold enough to attack basic constitutional rights.
