Here’s what I said on the topic of federalism.
To add some hard data to the discussion, let’s compare the degree of fiscal decentralization in the United States in both 1902 and 2019, based on numbers from the Census Bureau (click on Govt_Finances) and the Office of Management and Budget (click on Table 14.3).
As you can see from the chart, Washington now accounts for a much bigger share of overall government spending.

By the way, these numbers should not be misinterpreted.
There’s been no reduction in the burden of state and local government outlays. Indeed, there’s been a steady increase in such spending, even after adjusting for inflation.
Indeed, the fiscal history of the United States is a sad story about the loss of almost all constraints and limits that America’s Founders put in the Constitution in hopes of controlling the size and scope of Washington.
The bottom line is we now have much bigger government and it’s more remote because of centralization.
I mentioned Switzerland in the latter part of my answer.
Here’s the data comparing Switzerland and the United States. As you can see, Switzerland has been more successful in retaining genuine federalism.
Indeed, the two countries are mirror images, with nearly 2/3rds of government spending in the U.S. coming from Washington and nearly 2/3rds of government in Switzerland taking place a the level of cantons and municipalities.
P.S. Here’s what scholars from the Austrian School have said about federalism.
