Trickle down works in a perfect world but this ain't a perfect world. First of all, the Feds have continued to raise interest rates (while continuing to fail to address its balance sheet of $4,500,000,000,000) and there are bubbles in the stock market, junk bond bubbles and even bubbles in the crypto currency 'market', and I don't see any reason to feel good about avoiding a global recession by some time in 2019. The tax cut is essentially a 4.5 trillion subsidy to the corporations which typically get redistributed among themselves, and that's on top of the Federal Reserve 'subsidy' to the banks of around 6 trillion dollars (although the balance sheet still indicates 4.5) in the form of quan ative easing. When Bush gave out his 3.4 trillion in tax cuts (which Obama extended to the tune of another 6 trillion dollars in tax cuts), 80% of it went to the wealthiest individuals and corporations. The 2005 Multinational Corporation Repatriation Bill gave out a nice incentive to offshore corporate accounts that was basically a huge tax cut (bring your money back over here and get a 5% tax rate in exchange). So, where is all this money going? How much of that could have been invested in jobs if 90% of that revenue went to buy more stocks and pay off dividends? Look for corporations to use loopholes and to convert cash into liquid where they can so that they essentially have no taxes to pay at times. If previous fiscal policy and tax cuts did not generate investment in job creation why would the current tax bill be any different? Wages will not rise, real jobs will not increase and the deficit will enlarge to the point of sequestration.
