Bernie tapped into the amorphous socialism clamored for by today's young people who face dim job prospects while saddled by large college debts for degrees incommensurate with what's available in the job marketplace. This is the direct result of the takeover of public education from bottom to top by the left. It never delivers what it promises, except for hope.
As "millennials" replace the Baby Boom at the polls, their vote will transform America, and already has. Obama and Bernie were signs of this. Expect a return to high taxation of the rich, even larger federal government, and the transformation of existing welfare state programs into universal systems.
Like it or not, that's the future. Patriotism will take the form of socialism for Americans instead of for the world.
Now that Republicanism has thoroughly committed itself to globalism, libertarians are advised to take the money and run.
