Good thread. The clarity of the fact that "progressive taxation" is at it's core unfair has kept the Envy Merchants at bay for the most part. A few blips though:
tagej: You can't be aconservative when you wheeze out faulty logic like this:
"I disagree with a flat tax though, because in a flat tax system the people at the lower end of the scale end up paying a disproportionate amount of their incomes in taxes and fees etc. Even as a conservative, I'm for a progressive tax system -- but it needs to be made more simple, with fewer loopholes"
A flat tax 
IS PROPORTIONATE!!! A 10% flat tax would result in a person making $25,000 paying $2,500 in tax (1/10th) and a person making $100,000 paying $10,000 (1/10th). GET IT?!?!?
A flat tax WOULD be the simplest, fairest, loophole free method because you would just hand over a percentage off the top. The reason too many can't deal with it is because they've been so used to the escalating rate, "soak the rich", tax system that they've been convinced that leaving people with more money is somehow "unfair". You can't be a conservative with that kind of faulty logic. Free your mind!
This crap about any tax code change needing to be "revenue neutral" is another crock. All that means is will the government be able to steal enough money from the worker to buy the love of the selected constituancies according to this year's promises. (Xerox Man has it absolutely right in his sig's quote.) If you had to cut a check for every program that government comes up with, as opposed to having the money withheld, you'd start to wonder, "WTF is this about and why am I paying for it?!?" That's why they steal the money up front: So you CAN'T OPPOSE THEM!
Next!

EVRY SINGLE THING YOU GUYS SAID WAS SOME OF THE MOST RETARDED CLASS-ENVY BULLSHIZNIT I'VE EVER READ!!!!! I hope you can't vote because you're clearly too stupid/ignorant/pointless to be allowed to affect the political process! Take the rest of your moron friends with you too, mmmkay?
Listen up: SOMEONE WILL ALWAYS HAVE MORE MONEY THAN YOU!!! (Unless you're Bill Gates or Larry Ellison or the Sultan of Brunnai.) How does taking away their money help you? It doesn't! It's not like Al Gore is gonna whip a pistol out on Gates and take his money and then drop it out of Air Force One over your house.
Are you familiar with the term "bracket creep"? It's when you start making LESS net money due to taxes hitting harder due the next higher rate kicking in. Unfortunately, I can't remember where the brackets are, but for this example, let's say that there are three rates (15%, 27% & 40%) that kick in at $35,000 and $75,000 respectively. Also, these examples are overly simplistic because they don't take into account all the other taxes (state, FICA) and deductions and just focus on Federal Income Tax.
If you made $34,000 at the 15% rate, you'd pay $5,100 in tax and have have $28,900 left over. Now, say you got a 3% cost-of-living increase. You didn't get a promotion, you just had your wage adjusted to keep pace with inflation (a hidden tax BTW). That $1,020 increase would just nudge you into the next bracket (27%) which would mean you'd earn $35,020, but pay $9,455 in tax(!) and net only 
$25,565!!!:Q Your 3% raise would result in a net LOSS of $3,335 or a 12% reduction.:Q
Someone was saying something about progressive taxes being more fair?
Another example: A manager who makes $50,000 gets a promotion and now make $75,000, a 50% raise.
Before: $50,000 - $13,500 (27%) = $36,500
After: $75,000 - $30,000 (40%) = $45,000
A net 23% raise after taxes. That's fair?
You llamas working at Beast Buy obviously don't imagine a better life for yourselves, do you? Why else would you be spewing such nonsense about the need to punish success? Get over yourselves and stay the hell out of other people's wallets!
The comment about the gardner not getting a job was spot on. I do PC tech support. If Gates didn't create such a buggy OS, so prone to crashing, I wouldn't have a job!

 (Not to mention the economic benefits of the Information Age.)
