This term was coined by American Democrats to criticise Ronald Reagan. In Free Lunch, I have said it's not trickle down but Amazon Up. Trickle down is all sorts of mechanisms to take from the many and give to the few. In America, the subsidies to Warren Buffet are an example. In the U.S., one form of utility, the pipeline, is exempt from corporate income tax, which I have estimated at $3.4 billion a year. That's three cents a day per American. Customers are forced to pay the tax since this utility is a monopoly and the company is then exempt from paying corporate income tax. That's just upward redistribution. But, we always talk of redistribution as being downward. You want to have rules that encourage work, savings, investment and that reward people who work very hard. But, also do not force people down below to give involuntarily to people up above.
What are your chief observations about round-tripping of FDI such as those enabled by the India-Mauritius tax treaty?
