You can't have lower taxes unless you have less govt. spending. Why do think that the far left keeps demanding more spending? Its because they dont want lower taxes so they ensure that by demanding higher spending.
The spending is the tax, not the other way around.
I know how government budgets work and it's pretty fucked up.
Let's say in 2012, you have a budget for 1 million dollars... If you don't spend that million dollars in that year, and let's say, you only spend 500,000, then in 2013, your budget will only be 500,000... So at the end of 2012 departments go out of their way to spend any and all money left in their budget.
Whether they need to or not.
This keeps them getting a million dollars every year.
Budgets should be allowed to shrink and grow as needed... not just to keep a steady check coming in.
It's quite fucked up.
