Ideally the federal government virtually doesn't exist. While my inner anarchist wants no government, I'll explain this in a more palatable manner:
Federal Government's Duties:
1) Raise a military in times of war/act as a unifying body
2) Enforce the constitution (and interpret it, though states should have the right to deny the interpretation somehow)
3) Handle inter-state conflicts such as water rights, trade agreements, highways, etc.
Virtually everything else should be in the hands of the states. If they wish to change the constitution, it should require a change to be ratified in at least 2/3rds of the participating states' constitutions or for a constitutional convention to be held.
Oh, also, do away with the ninth amendment or heavily change it if you follow the US constitution. It's the source of virtually all this SJW bullshit.
