OK, I'll accept that you weren't intending to suggest that the government has primary claim on your income but you seem unaware of how your framing has been used by others to actually make that claim.
I can accept theoretically that you can separate the progressive structure of the federal income tax from spending decisions but in reality it is pretty hard to solve our budget problems by simply taxing the 'rich'--at least if you use the $250,000 figure that is most commonly used.
Here is a nice calculator you can use to see the difficulty: http://splitwise.com/taxes/
