Both plans are lunacy. Trump’s is completely detached from reality, fiscally. Ryan’s is the plan of a moustache twirling villain, but is slightly more rational in that it actually tries to pay for those tax cuts for the super rich by taking from the middle and upper middle class.
Trump’s plan is massive tax cuts for the wealthy with a smokescreen of populist tax cuts for the lower orders. His base will love that.
Ryan’s plan is completely unappealing unless you are a self-hating poor person or a completely self-absorbed rich person.
