There were three areas of failure at the G20 in Hamburg.
The most obvious and easy to identify was Donald man-child Trump.
I'll let this Australian reporter sum it up better than I could.
The second obvious failure was with the public at large.
"Welcome to Hell" was the first of over 30 planned demonstrations in the days before, during and after the G20 Summit. On Saturday, Hamburg Police said 213 officers were injured, at least 114 protesters were arrested and 98 detained over the three days.
Finally, there is the failure that really matters.
The Hamburg G20 might go down in history as the moment the international elite just couldn't hold it together any longer. For years, leaders of the most powerful countries have come together to cooperate on how to run the world: the G6, G7, G8, G20. Their watchword was stability.
...The international elite are divided. This should scare us, as such divisions can plunge the world into violence and disorder. But the situation is not hopeless...
This G20 will pitch the "strongmen" against the "moderates" - Merkel, Macron, Trudeau. The latter might look nicer, talk nicer and act nicer. Merkel has put climate change, migration and free trade on the agenda, much to the chagrin of Trump.
We shouldn't be fooled. The G20 agenda utterly fails to break with the tired, broken policies of the free market. In other words, those very policies which, by increasing inequality and devastating communities, turning everyone into a self-interested individual, have unwittingly given rise to the likes of Trump. And that's to ignore the "Trumpism" in European politics - the barbaric immigration policy at Europe's borders through which thousands of desperate migrants die in the Mediterranean every year.
Sure, Merkel wants cooperation on climate change and thinks globalisation should work for the many, not the few. Who can disagree? But what does that really mean? A desperate attempt to restore the system that was destroyed on the day Lehman Brothers collapsed.
The G20 agenda talks about the need for structural reforms to reduce debt. Like those deeply anti-social policies the European Union has imposed on Greece for the last eight years, which have devastated that country and its people?
As I recently pointed out, neoliberalism has failed.
The problem, as was on display in Hamburg, is that our elites have no Plan B.
