The only thing you need to know--- assuming you're not a multi-millionaire or billionaire--- is that Trump would try to enact the largest tax cut (mostly for himself and his country club friends) in American history. Obama has paid down 1/2 of the national debt. Trump's revenue slashing would VASTLY increase debt, to unprecedented levels. Attempting to cut huge amounts of the government not only would collapse the already teetering economy, it would set a time bomb set to explode when non-regulated industries like energy and banking had their ways with the environment and consumer resources.
If you liked what Bush did to the economy, you're going to love Clown Trump.
