On 60 Minutes, Rep. Alexandria Ocasio-Cortez (D–N.Y.) recently said "people are going to have to start paying their fair share in taxes."

Anderson Cooper then asked her what a "fair share" would be.

Ocasio-Cortez responded that in the past, "Sometimes you see tax rates as high as 60-70 percent."

Soon, that became the progressive plan.

But economic historian Phil Magness, of the American Institute for Economic Research, says that progressives miss an important fact: The high tax rates that America had in the past actually didn't bring in much revenue.

When rates were at 70 percent, Magness tells John Stossel, "A millionaire on average would pay 41 percent."

That's because rich people find loopholes.

Stossel says: Let the market decide, even though that means some get really rich, because economic growth benefits everyone.
