Nope, no bias there...
Yes: INVESTMENTS create jobs; WAGES are the result of INVESTMENT. Therefore, investment should be encouraged and favored.
Oh that's right... the Democrat party doesn't care.
If you spend your income on cocaine or gay favors, then it isn't available to invest.
If you invest it in non-productive crap like Solyndra, then it produces no income to tax.
But if you actually invest it in something which makes money, then it is taxed (a second time) at a lower rate. This is Romney's real crime here.
