GWB was definitely the worst president in my lifetime, exceeding Nixon by a long shot. Trump is going to make GWB look like a Lincoln or Washington.
Historians are going to mark November 8, 2016 as the date the American Century ended. Within a few years our currency will no longer be the world standard. The USA will be mired down in probably several new wars (pray not nuclear) caused by Trump's thin skin and enormous ego. The implicit constitutionally recognized right to privacy will be gone along with Roe v. Wade within a year. Inflation will start to ramp up then caused by the Trump tax giveaways, loss of US currency as world standard and rampart military spending. Europe, especially Eastern European countries, will be under intense pressure from an expansionist Russia which Trump will do nothing to stop.
In the longer term (5-15 years out) Social Security, Medicare, etc. will be busted. As someone already mentioned Obamacare will be repealed (and NOT replaced) probably by next spring.
The Trump family will actually become fabulously wealthy, along with certain friends.
Nuclear proliferation will abound-you think countries like Saudi Arabia, Korea, etc are going to continue to rely on the USA to insure their existence? The Iran agreement is now dead and Iran will ramp up its weapon production to counter the Saudi influence. If you are thinking of any trips to the Holy Land, to see the pyramids, or anywhere else in the Mid East you better get that vacation done in the next few weeks.
China will step into the vacuum left by the USA and will be the defacto world leader. The USA will be an oversize copy of the old British Empire in decline. A very large debtor nation where both capital and most good jobs have long since fled.
And the USA middle class, surprise surprise, will find out they have really fucked themselves and their future generations over.
France will follow our example, to be led by their neo-fascist. Even stable countries like Germany and Japan could also go bat shit crazy. The world is going to be much more dangerous in the near future.
And that's the upside. If Trump plays into his Caesar fantasies, look out world.
We are screwed, and screwed good, and have no one to blame but our own stupid selves. It's hard to believe that the USA descended so far and so fast from my parent's generation, the Greatest Generation.
If you call that surviving, you are welcome to it. Being ruled by a crazy uncle is not a formula for success.
