If these questions are bothering you, then Stephen Green's book "Good Value - Reflections on Money, Morality, and an Uncertain World" may provide some of the answers. But then again, why ruin a perfectly good question with an answer?
What is progress? Is it material wealth, or is it something more fundamental: the increased ability to create such goods as happiness, love and friendship (although we should not underestimate the part material wealth has in that)?
Why should I care? If I am as contented as can be expected and my world is well tended and well protected, why should I lift a finger? As Groucho Marx said, "Why should I bother about posterity? What has posterity ever done for me?"
Still, it's worth a try, especially when you can get the answers for free by reading the book online at www.archive.org. To "borrow" the book, simply join up - it costs nothing! - then log in and borrow.
