When I read this article few minutes ago I found the following phrases and quotes defining the characters of these people and justifying their acts-
...“It’s (money) an important tool. They don’t neglect it, but they also don’t worship it.”...
...“Part of this pressure to keep going is less about greed and more about insecurity that might be self-imposed,” ...
...“It’s about paying attention to what makes you happy and not just doing what our society tells us to do,” ...
... he and his wife simply didn’t care that much about material possessions...
... “We like to travel, and we’ll spend the money for that because it’s worth it having a real experience together.” ...
And when I went through the comments here, I found none so far discussing on any of the points above.
