A Thought about how lower Taxes ruined our economy

So the conventional wisdom about taxes all these year has been lower taxes are better. We've been living with this assumption since Reagan has been president. President Reagan followed the advice of Arthur Laugher and his supply side economics. But since that time we've experienced two phenomenas. 

First is that the middle class seems to be shrinking during this period of time. That also includes a decrease in jobs available to the middle class and a devaluing of the work that the middle class does. While the middle class is shrinking the upper class is not expanding they are simply increasing the gap between them and the classes below them. Our wealth as a country is gathering into fewer and fewer hands. This can be clearly demonstrated by the increase of the compensation of executive salaries while the workers at the middle and bottom of the cooperate salary structure have lost benefits and pay. 

Second, since the upper levels of society has received tax breaks we've experience several periods of boom, bubble and Bust. These periods have resulted in recessions and depressions. We've had the dot com bust, Saving and loan bust, Banking failures and stock market crashes. All of this has lead to an uncertain future for the people of the United States. Today for the first time in our history people feel the their futures aren't as bright as their parents felt their future were. 

So WHAT TO DO ABOUT THIS? It seems reasonable to revert back to a time when the upper class had less available money if they chose not to put their money into actual productive use. Raise the tax levels and give incentives to pay less taxes if they invest it in companies that actually provide jobs and value to our economy. This might result in a lesser growth rate, but it will also result in a steadier growth rate and allow all the classes to have a steak in our Countries future.
