This WSJ editorial on the sliding scale with lower capital gains taxes for investments held for a longer time frame proposed by Hillary Clinton, says there is no economic theory that shows one or two year investments are worse than longer term investments, and says investors who invest in startups and cash in after a year or two can then invest in other startups increasing investment capital. It points out that new startups are fostered better in an environment where capital gains taxes do not promote holding investments for a longer term. Hillary Clinton is calling for higher capital gains taxes on shorter term investments. The current rate is similiar to the 20% rate under Bill Clinton. George Bush lowered it to 15%, and president Obama increased this to 20% for couples earning more than $484,851 a year, and added a surcharge of 3.8%. Under Reagan it was initally 20% in 1981 and in 1987 as part of tax reform cutting the top income tax rate to 28%, it was 28%. Hillary Clinton's plan is for it to be based on how long investors hold their investment discouraging 1-3 year investment horizons- Year 2- 43.4%, Year 3- 39.8%, Year 4- 35.8%, Year 6- 23.8% or the current rate for the highest income bracket. Investments in infrastructure and long term research projects leading to new technologies and products require a longer horizon encouraging such investments. The Clinton plan appears to be a response to the tech bubble with investments in small tech changes and software improvements that have led to surging investment in startups in social media and other areas which have not yielded the productivity gains needed to support increase in wages- resulting in low productivity and low wage gains in the last decade....
