I agree, the right can not use the "uncertainty" argument any longer either.
The tax rates have been historically low on the wealthy since the Bush Tax cuts kicked in, and there was no "uncertainty" about how long they would last.
The wealthy didn't do shit to create jobs. Instead, they offshored as much as possible, and "increased productivity" by making one person do the work that 2 or 3 formerly did, without paying them any more money.
Job creation sucked under Bush, and many/most of the people who are out of work now LOST their jobs under Bush, when there was still "certainty" about the tax rates.
A capitalist will not STOP earning because the tax rate is higher... instead, he should be motivated to gear up production to generate MORE profits to make up for the amount paid in taxes.
