I believe that if you have some skin in the game even if its minimal its a psychological plus.
Furthermore, Trump plans to cut much government waste that we complain about all the time. This guy will do it instead of paying lip service like what we have gotten from politicians. Trump has set a target for 20% which is pretty good reduction. Reducing the government fat under the skin. I suspect he’d like to cut even more.
Trump could always put in a tax line for people who want to give more to government if it makes them feel better. *Grin*
