NUTS TO THAT!
Tax cuts cause economic growth. Read The Laffer Curve, etc. Stop reading Keynesian claptrap.
And even if tax rate cuts didn't stimulate growth, tax is theft. It's immoral, and therefore it should be minimized, not maximized. But you'll never get a Marxist to agree.
Keynesianism is exactly what you’re espousing. Higher deficits leading to growth. Not that it’s wrong, just you should be aware that you are a Keynesian.
