Technically, maybe, depending on how you define “federal income tax.” Social security tax is federal, based on income, and a tax. And more than 53% of Americans pay it. So maybe he was not right.
But obviously the point isn’t whether his number is correct. The point is that he said 47% of Americans consider themselves entitled victims and that these 47% can’t be convinced to take personal responsibility and care for their lives.
The point is that, if he actually believes that, he’s profoundly ignorant and completely out of touch with how 47% of Americans go about their lives.
