The myth that lowering taxes on corporations results in economic growth needs to die.

"A 2007 academic study by Roy Clemons, then a graduate student at Texas A&M University, that was based on earlier data, found that the tax break did not stimulate investment in the United States economy and that repatriated money was often used for disallowed purposes, like stock repurchases."

"While empirical evidence is clear that this provision resulted in a significant increase in repatriated earnings, empirical evidence is unable to show a corresponding increase in domestic investment or employment"
Also capital gains tax is unfair to lower income individuals. We can invest money and afford to wait a year to see gains (and the obscenely cheap 15% tax rate). Most individuals cannot even invest, yet alone let their money sit for a year.
I don't understand how the "tax cuts grow reinvestment" argument sways people. Investments into the business are deductible as expenses, meaning doing the exact opposite of a tax cut will actually drive reinvestment far more effectively. Cutting taxes allows for stakeholders to withdraw profits with much less of an incentive to reinvest.
Want to drive up the velocity of capital? Cut personal taxes especially on lower bands since people in these bands are more likely to spend that money on essentials and personal luxuries to make life better. Increased spending -- be it at the corporate level on growth, hiring, and research, or at the personal level on necessities and occasional luxuries -- keeps the economic engine going.
