That’s not how marginal tax rates work.

.. You know how it works, since you’re using it correctly below.
I don’t like this incorrect use to make a point.

“Higher taxes always lead to more government spending, less individual freedom, a slower growth economy, more Americans dependent on the government and greater income inequality.” — For whom?
The proposed tax rate isn’t for the common individual, is it?

I don’t think you’ve explained your position either. How would it help?

Also — is the proposed tax rate of 70% for individuals or corporations as well?
