Okay, so I tried out the tax calculator linked by the fleabitten primitive.
For the record, I'm kind of at the lower end of the income scale, but that's mostly voluntary on my part: I just can't get excited about making a lot of money.
Under Trump's plan, I'd pay $310 less.
Under Cruz's plan, I'd pay $280 less.
Under Messalina Agrippina's plan, I'd pay $20 more.
Under Methuselah's plan, I'd pay a whooping $960 more.
