It is critical to a responsive and robust economy that the USA maintain the current system of tax incentives balanced by tax rates. How else can the government provide economic stimuli when called for?

However, it is high time for some radical changes. Here a few ideas for your comments.

1. Increase the corporate rates by 25% (there has not been in increase in these rates for many years), and eliminate the current double-taxation of corporate profits by making dividends either tax exempt or subject to credit offset for taxes paid at the corporate level.

2. End all estate taxes--another flagrant example of double taxation and a Marxist concept to be sure.

3. Reinstate "Income Averaging" (remember good ol' Schedule G?). People who are working hard to advance themselves should not be penalized by having to pay taxes at the same rates as people who have been at given income level for many years. 5-year income averaging used to be the law and it is needed again.

4. To qualify for the Earned Income Credit one must be either a citizen of the United States or legal resident and all qualifing dependants must be as well. This will end the drain on our system by people who send their earnings to foreign countries.

5. Bring back the Investment Tax Credit and expand it to cover energy-saving appliances and vehicles (with higher than average fuel economies, not just hybrids), not restricted to business use only.

6. Remove the 7.5 % floor on deductions for heath care costs and allow all people who pay for health insurance to take these costs as an adjustment to income on the face of the 1040, as is the case for self-employed people now, but at 100%.

7. Create a special Veteran's tax credit to be used to offset 50% of all taxes on income, never to expire. Government won't be too quick to send people off to war if it means loss of tax revenues over their remaining lives.
