Once again your chart doesn't show anything, it merely shows that the Dow Jones averages increased during a certain period of time, it doesn't attribute it to actual economic growth or inflation. Even if it is inflation adjusted it doesn't take into account what sectors of the economy grew and which declined.
Remember the middle class and lower classes have to have money to spend in order for trickle down economics to work. You can give all the tax cuts to GM/Ford/Chrysler that you want but they aren't going to be able to provide jobs when Joe Average can't afford that shiny new Silverado. It works when the economy is going well but for a tool to rescue the economy trickle down economics is quite disastrous.
