Hypothetical: You have just taken a job as a lobbyist for a tax reform group. They're letting you lobby Congress for the kind of tax system you think we should have.
What do you lobby for and why?
A flat tax. One where everyone pays the same percentage on their earned and unearned incomes.
No tax breaks for the rich, no loopholes, no writeoffs, just a flat percentage tax rate for all americans.
Why? Because that would be fair.
Okay, based on my response to the Sgt, you and I are on the same page. But let me play devil's advocate here for a bit.
A Constitutional expectation of the federal government is that it will promote the general welfare. The general welfare could be seen as promoting the traditional family, promoting charity, promoting home ownership, promoting new business startups and business expansion, etc.
So long as this is applied evenly across the board without respect for the standing of any citizen, is there no room even in a flat tax for the government to promote such activity?
