No quick fixes

Even if Trump were to disappear tomorrow the US would still be left with a grave problem. One half of the country mistrusts and even hates the other; something which has been slow cooking like a stew for decades now. 

Trump was simply a facilitator to let the most unseemly instincts of many see the light of day. The racism, the misogyny, xenophobia, etc. were encouraged to percolate to the surface accelerated via a social media landscape ripe for expressing frustration and hatred. 

The US has never properly dealt with its civil war and the south and middle heartland retain some of instincts to suppress minorities bolstered even more through the influx of undocumented Latinos of recent years. The GOP has used this as culture war fodder to distract its low information base while it takes away their resources. 

This isn't going to be resolved after Trump leaves. Gun violence and corrupt political practices have only made things worse as corporations and special interest groups curry favor through their superpac donations. 

No, this mess will take decades to fix and, as the empire slowly crumbles, it will allow many who want justice to advocate for concrete solutions that may see the country rise once again to a level where fairness is no longer a dirty word.
