Make America Hate Again.
A minority of voters elected a rascist, misogynistic fearmonger (and uncharged sex offender), who now has license to use their fears to line the pockets of his cronies. Manufacturing jobs are not coming back in any meaningful or lasting way. Automation marches on, improving the quality of products while reducing the # of employees. Aggressive international trade tactics will jack the price of everything this country imports, which will cripple retail sales. Add 30% to every price in Walmart, etc. Other countries will raise tariffs on US goods they import. Demand for those products across the world will fall, further reducing our economy. Gas, oil, mining will see a brief resurgence as environmental safeguards are rolled back. Prices for those commodities will fall as surpluses increase to glut. So permanent environmental damage will again surge as the unpaid price for a very temporary boomlet. Meanwhile, nonconsumptive technologies improve in other countries while we languish. The world will continue to act in recognition of catastrophic effects of climate change; we will be seen as pariahs and further isolated from global cooperation. Russia will continue to infiltrate our government and industry, taking all they can steal. While our leadership sells us out for their own enrichment.
The president will continue to attack everyone and everything he disagrees with or doesn't understand, reminiscent of those who voted for him. This will add to gov't gridlock, as already-disillusioned federal agencies and employees will sandbag his efforts to "reform." Congress, which already hates and distrusts him (remember the primaries?) will punish his hubris by undermining him, then abandon him as the midterm elections approach. Democrats and others in the voting majority will seek to repay the Republican majorities in Congress by stonewalling in a replay of how Republicans stonewalled Obama's agenda.
The guiding principles of America under Hump will be winning unnecessary conflicts @ home and abroad, no matter the cost to Americans; bald-faced lying in service of personal gain for the 1%; inflammation of racial, economic, gender and ideological factions. But mainly this, which is already well underway: Divide and Conquer. Make America Hate Again. Divided we fall.
