I agree. The tax bracket system is lame. Everyone should pay the same percentage. If you want more money, earn it. It's a shame that people have to pick up the slack for others just because they are successful.
< For the Record: I support that people who make more should pay more. The fight is over 'How Much More Shoudl They Pay'>
The problem with a Flat Tax begins with poor people getting disproportinately hurt.
To create a ficticious example: Let's say 20% is the magic number for Federal Income Taxes
(it's roughly approxmiate to most of the US populatly now, BTW). If you make 100K then you pay 20K in Federal Income Taxes. You may not like it. But it's doable without too much trouble.
OTOH, If you make $30K, then 20% of that is $6,000. Leaving $2K a month
(less Social Security, State/Local Taxes) to pay rent/bills, and feed your family with. This hurts a LOT more than the first example.
(You'd pay about $4K now)
..and if you're making $20K, then you'd have to pay the Federal Government $4,000
(instead of the current $2500~ish). Leaving just $16K to pay the State, Social Security, Rent, Food.... Here in the Northeast USA, where rents alone are $800~1200/month you would be Homeless if you had to support yourself on that salary. Hell, you probably are already.

Now: When you look at the per capita and adjust for the number of people at a given salary level, you can absolutely get the Middle/Lower to less than 20% and make up the difference at the treasury level on volume. But there's a problem with that: The upper working classes, middle class, and "rich" already currently pay more than that. In other words, the tax tables already scale up as you move higher. So... Where does the balance come from...
Uh Oh.... Does this means that a "Flat Tax" essentially amounts to saddling the poor with more taxes while giving the rich a break???
Why - Yes. Yes, it does.
The IRS's forumlas for estimating:
The upper brackets:
At $82,250~171,550: 20%, plus 28% for any amount over $82,250
At $171,550~372,950: 24%, plus 33% of any amount over $171,550
Over $372,950: 29% of the first $372,950, and then 35% of any amount over.
The lowest bracket currently pays 10% of the first $8,250, and 15% of any amount up to $33K.
In implementing a Flat Tax, you're either keeping the upper brackets steady and f*cking the Mids and destroying the Lower.
{30~35% on $20K!!!}
Or You're keeping the Middle steady while f*cking the Lower and giving the Upper a break.
{25% on 20K (+10~15%), 25% on the mids (about the same), and 25% on the Upper (5~10% LESS!)}
Or you're giving the Highs a Huge break and giving the Mids a break while continuing to screw the lower.
