So much for "making a bigger pie".
Duh. There is a bigger pie and more money being taken in.

IIRC it's conclusion was that the increased spending wouldn't be able to yield back even half of what the tax cuts actually cost,
? The tax cuts brough in more money so they didnt cost anything. Their not tied to spending. The samething happened under Reagan. He doubled the amount of money coming in. But for every new dollar he brough in congress spent two. Dont blame the deficit on the tax cuts. Blame it on the spending where it belongs.
