I would work more in a flat tax environment, as most hourly workers that I've talked to would also. The main reason is the time and a half paid for overtime. the trouble for lowly paid workers is that they would have to work more to reach that equilibrium point you were talking about above. That's the point were the flat tax equals the progressive tax.
Interesting conversation but I admit to not have thought much about it and the consequences.
Babb's you made a wrong assumption above when you said I love my job, I don't. 

Since working longer hours only affects hourly workers, then let's examine your claim a little bit closer.
2008 Tax BracketsTax Rate............. Single........................... Married Filing Jointly
10%................... Not over $8,025..............Not over $16,050
15%................... $8,025 - $32,550............ $16,050 - $65,100
25%................... $32,550 - $78,850........... $65,100 - $131,450
28%................... $78,850 - $164,550.......... $131,450 - $200,300
33%................... $164,550 - $357,700......... $200,300 - $357,700
35%................... Over $357,700.................. Over $357,700
Let's simplify and only consider one of your single co-workers, who pays 28% on his income tax. Also, let's round the bookends off to $79K and $164K, so that there are 17 increments of $5000 between $79K to $164K (i.e., diff between 164,000 and 79,000 = 5000*17 = 85,000). Obviously, between the endpoints, the tax rate remains unchanged, kind of like a flat tax. Your co-worker can work longer hours and make
up to $85,000 more than he currently hauls in each year and not be penalized. But this argument is measured at the margins only--going from a lower tax bracket to a higher bracket.
$5000 over the 28% tax bracket would put him to the 33% tax bracket. That $5000 jump results in a $250 increase in taxes paid per $5000 of additional income ($1650 from $1400). So your lame complaint boils down to this: For an additional $1000 made at the margin, you will pay an additional $50 ($330 from $280) in taxes than had you not leapfrogged into the higher tax bracket.
That is so lame. I can't believe you goofs would forego that additional $1000 because it will cost you $50 more since you got bumped into the 33% tax bracket

And you know what, you wouldn't turn down that $1000, which is why I maintain that you guys glom onto these "Joe the Plummer" slogans that prey on everyone's inner victim
