The Buckeye Institutes doesn't understand simple things

The Buckeye Institute just released a tool to compare salaries. The only trouble with this hackish tool is they don't understand how anyone is paid apparently.

In their effort to make public sector workers appear over compensated, they add vacation and sick pay to salaries, without understanding sick and vacation pay is paid instead of salary, and therefore can't be added to create a juicy big total salary they can get all indignant about.

What kind of a "think tank" doesn't understand the basic principles of employee compensation?
