I did prove it. When Bush’s tax cuts kicked in revenues went down. I also posted a report you didn’t want to read from President Bush’s economic advisor admitting that revenues would not catch up with where they would have been.
And the principal is far from valid. I’ve posted links to reports and studies you’ve pettily waved away. So why don’t you pony up your own evidence instead of sniping.
You’ve given the Obamaview for one, and you’ve ignored Reagan for two. So you pettily wave away the principle.
