Why do Republicans want to add 4.4 trillion dollars to the debt by extending Bush tax cuts?

You still don't get it; do you? First. The tax cuts benefited all tax payers. Second. Reducing taxes increases economic activity causing more taxable events thereby increasing overall tax revenue. It worked when Kennedy did it, and when Reagan did it, and when Bush did it. I am having difficulty explaining this on a third grade level so you can understand it.
