When you see spontaneous social protests erupting from Tunisia to Tel Aviv to Wall Street, it’s clear that something is happening globally that needs defining. There are two unified theories out there that intrigue me. One says this is the start of “The Great Disruption.” The other says that this is all part of “The Big Shift.” You decide.

Paul Gilding, the Australian environmentalist and author of the book “The Great Disruption,” argues that these demonstrations are a sign that the current growth-obsessed capitalist system is reaching its financial and ecological limits. “I look at the world as an integrated system, so I don’t see these protests, or the debt crisis, or inequality, or the economy, or the climate going weird, in isolation — I see our system in the painful process of breaking down,” which is what he means by the Great Disruption, said Gilding. “Our system of economic growth, of ineffective democracy, of overloading planet earth — our system — is eating itself alive. Occupy Wall Street is like the kid in the fairy story saying what everyone knows but is afraid to say: the emperor has no clothes. The system is broken. Think about the promise of global market capitalism. If we let the system work, if we let the rich get richer, if we let corporations focus on profit, if we let pollution go unpriced and unchecked, then we will all be better off. It may not be equally distributed, but the poor will get less poor, those who work hard will get jobs, those who study hard will get better jobs and we’ll have enough wealth to fix the environment.

“What we now have — most extremely in the U.S. but pretty much everywhere — is the mother of all broken promises,” Gilding adds. “Yes, the rich are getting richer and the corporations are making profits — with their executives richly rewarded. But, meanwhile, the people are getting worse off — drowning in housing debt and/or tuition debt — many who worked hard are unemployed; many who studied hard are unable to get good work; the environment is getting more and more damaged; and people are realizing their kids will be even worse off than they are. This particular round of protests may build or may not, but what will not go away is the broad coalition of those to whom the system lied and who have now woken up. It’s not just the environmentalists, or the poor, or the unemployed. It’s most people, including the highly educated middle class, who are feeling the results of a system that saw all the growth of the last three decades go to the top 1 percent.”
