In fact, let's go back and look at what the Founder's intent was. They clearly laid it out in the Preamble.
We the People,
1. In order to form a more perfect union, The Articles of Confederation didn't work and caused more problems then it solved. Hopefully this will work out better.
2. establish justice, To establish courts to try cases to ensure contracts are upheld and bad people punished.
3. insure domestic Tranquility, That whole states and people fighting each other.
4. provide for the common defence, Despite the British spelling, this is were the 2A comes from.
5. promote the general Welfare, Do note the difference in wording from the statement above. Provide vs promote. Provide means "to make (something) available : to supply (something that is wanted or needed), to pay for or ensure". Promote means "to help (something) happen, develop, or increase" or "to contribute to the growth or prosperity of". The best way for .gov to promote the general welfare is to get out of the way.
6. and secure the Blessings of Liberty to ourselves and our Posterity, To not become an authoritarian government that destroys the freedom of the people, by severely limiting the power of government over peoples lives.
So there it is.
A better government then either monarchy or the one established by the Articles of Confederation, with unbiased jury courts, in a civil society, protected from all evils, allowing people to live as they see fit, in freedom for themselves and their children.
See it's not so hard to understand what they were driving at. However, the modern leftists look at .gov to be a force for good, when all a .gov can do is destroy. Which is probably why .gov's are really good at military stuff.
