From John Hinderaker writing at PowerLine:

… On the Left, a “wonk” is any liberal who can multiply and divide.

This regards a proposal to address income inequality by seeding everyone with a small taxpayer-funded trust fund at birth.

This actually is a pretty good idea (and one that has also been made in different formats on the left and right). The difference is that the people on the left do the math wrong, and then run with it.

Then he quotes from a reader’s contribution about widespread innumeracy on the political left:

But, as our reader says, this kind of magical thinking on the Left is not unique to Ornstein. On the contrary, an inability to understand the most basic principles of arithmetic constantly dogs liberals. How else did we get Obamacare? Moreover, Ornstein was not alone. Didn’t National Journal have an editor who read the piece and said, “Whoa! $3,500 to $700,000 at 5%? Did you check the math?”

Please note that the current version of the linked article does acknowledge the math mistakes in a footnote.
