This is something people are missing about the "alt-right" movement, it's not particularly right wing economically, it's certainly a different beast from the neo-cons. In Australia our equivalent is probably the one nation party, but they are to the left of our Labor party.
> I think that partially the democrats have been hijacked by this immigration, tolerance, ... ideology. It has gone too far. Traditionally, of course, the right is pro-immigration (cheap labor, acceptance of very weak employment conditions, tolerant of outright abuse and exploitation), and the left is anti-immigration, because they're trying to improve the position of the poor in society. Improving that position through scarcity of course works.
Yes, the left needs to go back to it's base and represent the working class. They've put for too much energy into playing wedge/identity politics and lost the working class to the likes of Trump.
