Both have happen and both have had an impact on the economy.

The supply side works in the scope of attempting to find the optimum tax rate that the people can handle and still increase productivity.

Now there are many ways that supply side economics fails - but attempting to find the optimum level is not one of them.
A reasonable answer. Not too far from my own view, at least in regards to what has been affecting the economy. It's much more complicated right now than a simple taxes go down = tax revenues go up. Which has been the entire point of my posts in this tread, I think.
