People making 10's of millions typically only pay around 5% tax, if any. They can afford really good tax attorneys and offshore shelters.
Though again your analysis doesn't mesh. If you are personally earning in excess of $250k in take home profits as a small business owner, how does an incremental increase in taxes on your take home profits affect your business? I can see how it might affect your lifestyle and personal consumerism, but it shouldn't have any impact on your business at all. Any money you spend on your business reduces your income, and isn't subject to taxation.
I'm a small business owner. I run a solo law practice. Any money I take out of that practice for personal income is going to be taxed as personal income. If I take out $250k, I get taxed at around 36%. Under Obama's plan, anything I take out over that would get taxed at a higher rate that has yet to actually be set, but it's still money in my pocket. If I couldn't afford to take that money out of my business, then I wouldn't take it out to begin with. I'd leave it in and use it to pay for expenses. Taxes are irrelevant in that decision.
There is no rational relationship between my business expenses and my personal income tax, since I only get taxed on the money I take out of my business after I've already paid its expenses. Raising my taxes would have zero impact on my business, other than perhaps a desire to earn more money to compensate for the increased tax so I could maintain my lifestyle.
All this nonsense about liquidity and credit is a straw man, designed by the right wing to confuse voters who don't understand basic tax and business issues. Obviously it's working, though it's a shame people are fooled so easily by such blatant misinformation. Apparently all you have to do to confuse the unsophisticated is throw in a few words they don't understand like liquidity.
And let's face it, if you can bring home $250k per year, you should be able to manage that income to live a good lifestyle and take care of your family. As long as you don't go crazy and buy a mansion you can't afford or waste your money frivolously, you really should be doing a lot better than say 95% of the population in this country.
This actually comes back to an old issue I raised a few years back about how poor white Republicans all think they are going to be rich someday, so they like policies that favor the rich. The reality is most will stay poor, or at best rise to middle class, and never benefit from those policies. How many US ALFAns do you think would actually be affected by an increase in tax on personal income over $250k? Like most online communities, ALFA is probably ahead of the curve on income. Still, I suspect *none* of the ranting right wingers would, or ever will. Do you honestly think Danubus is going to start bringing home $300k anytime soon? Heck, do you think Joe the Plumber will? Well, given his celebrity he may actually have a shot... but without that his odds of ever breaking out of his current income level given his age were pretty much nil.
Anyway, back on topic....
