My point is that a real look into "better" will often (probably! Not necessarily!) lead a person to minimize his or her ill effects. Naturally, being decent, they'll try to maximize their good effects. I pointed to a tradition like zen to evoke minimalism, to evoke noticing the smallest details. There are certainly many ways to improve.
I guess I spoke in a strong way so that my words wouldn't be immediately lost. If it sounds like I'm devaluing too many just plain good aspects of humanity then I can say I didn't mean to say that.
Now...I do quibble with the set of facts you offer that indicate the now is the best. Yes, life is so good for so many. Though we are clearly not in balance. We are heating up the atmosphere and we don't have a solution. That is an actual problem, right? Yes, it's easy to ignore. Easy to hope that "something" comes along. But I don't call it responsible.
