I was disappointed to read Donald Trump‘s tax plan today. In recent weeks, Trump has been talking a pretty progressive game on taxes. Many of us, myself included, speculated that Trump might be a bit left wing on this issue and might be attempting to shift the Republican Party a to the left on economic issues. Unfortunately, this appears to have been wishful thinking. Trump’s new plan is almost precisely the same as Jeb Bush‘s and Mitt Romney’s. This still puts him to the left of flat tax and fair tax candidates (Carson, Cruz, Paul, Huckabee, Perry, Walker all explicitly endorsed one or both, while Rubio and Kasich have expressed interest in ultimately going to a flat tax), but it puts him to the right of Hillary Clinton and far, far to the right of Bernie Sanders. So let’s talk a bit about how the Romney/Bush/Trump tax plan works, why it’s so disappointing, and what the differences are between the various versions of the plan.
