And the number of people — now armed with cellphone pictures and directions from human traffickers — trying to get out of the World of Disorder into the World of Order is at all-time highs, producing nationalist/populist backlashes in America and Europe.

This is all new and accelerating. But the big Western parties that dominated politics since World War II tended to be built around a set of rather stable left-right binary choices: the interests of capital versus labor; big government, high regulation versus small government, low regulation; a more closed national outlook hostile to free trade and immigration versus a more open internationalist outlook open to free trade and immigration; social norms to be embraced and social norms to be banned, like gay marriage and abortion; and economic growth versus environmental protection.

Ruling and opposition parties tended to be combinations of these big binary choices. But nowadays they just can’t contain and balance many of the new choices that parties, citizens, companies and communities have to make to thrive amid all these climate changes.

If I work at a steel mill and am a member of the steel union Monday through Friday — but on Saturday I drive for Uber and on Sunday I rent out my spare bedroom on Airbnb — are my interests with capital or labor, with more government regulation or less?

If I am a regional electric utility led by Republicans for decades — but am now investing in wind and solar because they’ve become cheaper than new coal and my customers are demanding climate-protecting clean energy — am I for Trump’s tariffs on the cheap Chinese solar panels and his efforts to force me to keep using coal?

Which party has a plan to pay for education in an era when lifelong learning is now vital for lifelong employment? How do we fund the kind of “perpetual education” that The Washington Post reported on recently, like the University of Michigan’s Ross School of Business, which just “launched a scholarship program that pays for graduates to take classes there forever, and the number of students is slowly growing.”

I detest Trump’s policy of separating immigrant kids from their parents. But how do Democrats think we’re going to manage the flow from the World of Disorder? In its annual report last week, the United Nations refugee agency said there is a record-high 68.5 million migrants, including 25 million refugees, wandering the world. And how do Republicans think we’re going to keep these people in their homes when Trump opposes all climate change mitigation and family-planning assistance for the developing world and most foreign aid?
