The only rationale for cutting corporate taxes is boosting the stock market

"This begs the question of what are these companies doing with all that debt? The next four charts show capex, R&D, share repurchases, and dividends as a percent of operating cash flow, respectively. The trends are unmistakable. Capex and R&D investments have nearly halved since 2000 and have been cut especially hard since 2008 while share repurchases are basically range bound at a high level and dividends have been on an unabated uptrend. Together, capex + R&D + share buybacks + dividends = 111% of operating cash flow. Debt must be issued to finance that which operating cash flow cannot fund, and this after slashing reinvestment in the capital stock. This is to say, North American Staples companies are issuing debt and eating themselves from the inside out to finance dividends and maintain stock buy backs."

So . . . in this sector at least, approximately 77% of operating cash flows are used for stock buybacks and paying dividends. LOL! There is no need for Congress to allow accelerated expensing of capital investments or lower corporate tax rates. Companies have plenty of money to invest. They simply choose not to because their large share owners and Wall Street want the money instead. I'm cool with that but Congress shouldn't be putting more money in their coffers because the money won't be used for investment.  It will be used to increase stock prices. 

Cutting corporate taxes will not benefit the economy or workers. Its simply payback for campaign contributions from corporations and the wealthy.
