Bureaucracies by their nature are corrupt, inefficient and wasteful. That's undisputed and universally recognized. Governments face zero market discipline and competition to keep them honest. They are the monopoly provider of services regulated under their control. So they set the price and tax the citizens. Beyond Defense, Courts and Law Enforcement, there's not much productive activity the Government engages in.
Governments always spend more then what they take in. Collect 1 Trillion, spend 1.2 Trillion. Collect 1.2 , spend 1.5. Politicians buy votes by creating social programs paid for with taxpayer money. Taxpayers are stupid and think they're getting a free lunch. This is why growing Government is a very foolish idea. It suffocates the real economy, is tacitly accepted by the idiots who think they're getting a free lunch, while the public debt is run up to stratospheric levels. Humans have tried this before. Ends in tears when the golden goose is killed and/or the credit card is maxed out. Don't confuse reserve currency status with Americas actual productivity. Americans are living off the coat-tails of reserve currency status. When that ends by running up the debt, they'll find they're much less wealthy then they thought they were. Delusions of grandeur. Pride before the fall etc.
