The reasonable set of ground rules seem to favor states over the will of the majority of the population. It is possible to change the constitution with states representing only 25% of the population. And remember you'd only need a majority in each of those states so could be way less of the population.
Overall the system seems flawed in that instead of having clearly delegated areas of responsibility to states and then doing the federal system as based on the population of the whole country it muddled areas and then made a federal system that couldn't respond to the population.
There are clearly delegated responsibilities to the states... the 10th amendment specifies as much... that the govt has grown beyond this wouldn't have been stopped by a parliament any more than the current system.
The 10th amendment isn't clear. Too many areas are dual responsibility. That's never going to be clear.
I'm being a bit hyperbolic only to make the point... I don't think anyone's "rights" should include forced labor of anyone else. So certain things, even food cannot be a right... I would think that public lands and a right to hunt/gather or even some level cooperative gardening/farming might be okay as a middle ground though.
