There is NO school of economics that justifies tax cuts for the 'trickle down' effect. Let me make it very simple for you. Conservatives believe that money in the private sector is more productive than money in the government's hands. Therefore money in the public sector should be limited ;taxes and government spending minimalized as much as possible. That is the policies of Hayek ,and Friedman ,and Laffer among others.
Your policies by contrast guarantee statist capitalism with all the cronyism you decry . In fact ,I would say that it is Keynesian economics that is really a so called 'trickle down ' theory . The Leviathan takes wealth from producers and trickles a small portion of it through their patronage machine to give a small percentage back to 'the Public' in the form of payoffs .
