Thank you for sharing your thoughts on this important topic.
I'm not sure that I agree that the lives of 99% improves while 1% get richer but in saying that - I think that I understand where you're coming from eg. living longer, shelter, water etc.
This stat from my last post jumps out at me:
The incomes of the poorest 10% of the worlds population increased by less than $3 a year between 1988 and 2011 (or $69 a year in 23 years), while the incomes of the richest 1% increased 182 times as much.
