The basic duties of national government
The purpose of national government is to:
protect its citizens from outside interference - a military defense
protect its citizens from each other - establish and enforce a uniform criminal law
protect its citizens from their economic system - create and regulate a common currency, establish and enforce regulations
ensure that the basic needs (food, housing, education, healthcare) of all current and (to whatever extent possible) future citizens are met - remove the "profit motive" from these industries as much as possible so that public tax dollars are spent efficiently and effectively
A new Constitution is needed which enumerates these values in an unambiguous way. We can't allow future leaders to have the leeway to undermine these core values no matter how much the billionaires pay them!
