The system is designed to put the two levels of government at odds with each other, just as it is designed to put the three branches of government at odds with each other. The genius of the constitution is that it delegated certain powers to the Federal government, gave the rest to the state governments, and let them fight over the gray areas. Freedom and responsible government - the goals of the constitution - are merely a byproduct of these two governments (and the various branches) squabbling with each other - that is the genius of the design.
Each level of government has some areas where it has clear authority - the Navy is clearly a Federal issue, keeping the streets clear of horse poo was clearly a local issue. Everything else, including the army (well ordered militias) was left “a little grayer”, and the two levels of government are supposed to squabble.
The other important facet of federalism is that the more intrusive powers are supposed to be more local powers - the idea being that each individual state could better decide what was important to regulate in each given state. The (I think unintended) byproduct of this is that if people don’t like the laws of a community, they can vote with their feet and leave. For example, because of California’s tax, rent control, and labor laws, I moved from California back to Florida - a costly transition for sure, but one less costly than me moving from the United States to the Cayman Islands (come to think of it…).
This maximizes freedom, because (1) states must compete with each other and (2) I can move around to find a government more to my liking if that goverment is local rather than national.
That is why I am a staunch Libertarian at the National Level of government, but I am “more okay” with local, tax-funded, “free” health clinics; local public education; and local bans on pornography, gambling, and guns. If you don’t like it, leave - it is less expensive to “move to another town”, involving a longer commute, than it is when the Federal governments policies force you to change countries.
And frankly, I think that intrusive local government power maximizes my Liberty, because I want to live in a country where gambling, pot, prostitution, and walking naked downtown through the crosswalk with a leather-clad submissive on a chain is legal. However, I want to raise my children in a local town/city where those activities are illegal, and the town puts a manger scene on the public lawn every year… and I want to live in a very local community where my neighbor does not have a pink house.
- It’s okay, you can call me a “Public Choicer” if you want.
