Whether our peak years are ahead or behind us depends on whether we respond to the challenges we face worldwide and at home with consequential actions or causal reinvention. Because the fundamental principles under which we operate are broken, and our lies are the depravity of reason that makes us fail.
We must not preach to the world that our success so far has come from the excellence of the systems we built, it comes instead from the tenacity of our people. We, the people, succeed not because but despite our flawed economics.
Take freedom, for example, none of the systems we preach to the world as free (democracy, stock-markets, governance, etc) obey the most rudimentary principles of freedom. Instead, we deploy an absolutism of freedom, using an oligarchically controlled harness of freedom (rather than the relativity of freedom that encircles the world) we expect the world to adopt. And many sovereign cultures six-thousands years older than us are rightfully not easily convinced we have our ducks in a row.
