Power & wealth have toxifying effects on those who accumulate such. Their opinions and decisions become increasingly self-centered, careless of the various balances of the world around them.

The end stage of capitalism was always tyranny, and it was important for that to be understood and guarded against via quality education for the masses, plus regulatory and oversight bodies backed by science, facts & reality. That and socialistic political practices, of course. Also of course, a high regard for sustainability and respect for habitat and nature's web.

In the end we have failed at too many of these things.
