The solutions will flow from decentralization, not from big, centralized national or multinational governments. From Charles Hugh Smith at oftwominds.com:
Solutions abound, we just have to look for them in the right places.
Despite my reputation as a doom-and-gloomer, all of my work is about solutions. The first step in identifying realistic solutions is to dispense with the distracting clutter of fantasies, a process that is dismissed as doom-and-gloom. But if we latch onto fantasies as solutions, we can’t proceed to real-world solutions.
For four generations (80 years), we’ve become accustomed to seeking solutions from the federal government. This reliance on large-scale solutions began with the federal responses to the Great Depression and then gathered steam in World War II and the Cold War. By the 1960s, federal programs, policies and spending were the go-to solutions for every problem.
The federal government tends to be reactive. This is the nature of government, which is naturally dominated by elites and entrenched interests whose goal is to maintain their share of wealth and power by keeping the status quo in its current configuration. Any fundamental change that threatens powerful interests is naturally shelved.
The net result is the federal government only instituted environmental-protection regulations after American rivers caught fire. It takes a tremendous level of national pain to overcome the resistance of entrenched powers in the central state.
