You may ask how the American Federal Government is able to maintain one of the largest fleets in our sector of space when it lacks an Income Tax to support it. The simplest answer is that the Federal Government cannot directly tax American Citizens. It CAN however tax the American States, and require that they hand over a part of their tax earnings to the Federal Government. But the States often display reluctance to hand over vast amounts of money to the Feds, so they have to keep such taxes to a modest level that the States are willing to pay. It is much easier for the Feds to require territories and colonies who do not have Federal Representatives to lobby in their favor to pay their taxes. Those taxes can be…much more lucrative to the Federal treasury than relying on the largesse of the State Governments. You may infer from this that the Federal Government of the United States of America is not universally loved and adored by all American territories and colonies throughout the galaxy. You would be accurate in that assessment. But when an American battle squadron those taxes help build stops by for a friendly visit, they are most certainly welcomed with a smile.
