I HAVE TO THINK ABOUT THIS, BUT MY FIRST INSTINCT IS TO SAY, "YES, THE GOVERNMENT IS WAY TOO BIG" AND WE NEED TO SPLIT UP SOME OF THE FOLLOWING:
The Federal Government Has Too Many Issues on Its Plate
Another reason to decentralize is to end a situation in which government shutdowns are more likely due to the broad scope and complexity of the federal budget and federal responsibilities.
In the United States, the federal government's prerogatives have expanded over the past century to include everything from old-age pensions, to highways, to health care regulation, to farming subsidies, and much more. This has all been added on top of the more traditional federal prerogatives of foreign policy. It's only natural then that the likelihood of shutdowns would increase as the number of areas for political conflict increases.
After all, the current shutdown does not come out of only a dispute over of a border wall. It is a larger issue that stems from the fact that the Democrats want to use the wall's potential funding for a myriad of other uses. And, the larger the federal government has grown, the possible targets for government spending has grown ever larger.
Moreover, even the issue of building border walls was not always a federal issue. Prior to the late nineteenth century, state governments were the governments that dealt with the issue of limiting migrants in-flows. Although some conservatives now create ornate legal arguments in attempts to prove immigration — a separate issue from naturalization — has always been a job of the federal government, the actual historical experience makes it clear the federalization of immigration policy is itself a later innovation.
So, we're now left with a federal government where the president and the legislature can argue endlessly over every little thing under the sun. If it's the federal government's job to control and fund everything from cancer research to national parks, then it's only matter of time until we endure a political impasse over one of the countless issues being discussed.
Nor is it just the scope of issues. The sheer size and scope of the United States is itself problematic. The US is so large, and culturally and demographically diverse, that significant disagreements over how federal prerogatives ought to be used are inevitable. A less fragile and more responsive system grows out of a decentralized political system that allows for diversity in policies that affect travel, education, poverty relief, and more. If education policy, for instance, is decided at the state level, then we can be sure we'll never see a federal shutdown over funding of schools. It simply becomes a non-issue at the federal level.
If you think education is expensive, try ignorance.
