'It works every time it's been tried' blares the conservative radio host of your choice. But not so fast...here's how that myth breaks down. If an economy is growing at a very fast clip and increasing in size year after year, that is one thing. Under that circumstance (as was the case in 1965 when our upper rate was lowered from 91% to 70%) then it is indeed possible to garner more tax revenue at a lower rate of taxation because you are, in effect, taking a smaller bite of a bigger pie. But this is a temporary result and depends on the economy continuing to expand. And since a prime factor in the continuing growth of any economy is that a nation stay up to date on modernization and maintenance of its infrastructure, that means this formula for increasing revenue by lowering taxes must inevitably be reversed if a nations economy is to stay strong. Nothing is static in economics!
