New Series: Is it true?

by JS

I sometimes encounter arguments in Op-Eds and wonder whether these statements have supporting evidence, so I decided I’d ask the Internet.

Here’s a snippet from the Washington Post today:

If rewards for America’s entrepreneurs and firms are reduced through higher marginal tax rates, their incentives to earn, invest and create jobs will be diminished.

Is this true? It seems like a simple enough statement that I should expect to find an easy justification in some economics textbook somewhere. Unfortunately, I know nothing about the field, so I’m asking the Internet.
