...The society frowns at me, calling me a full-time bum...And the result of this simple life is inner peace and equilibrium. The Buddhist wisdom is real, less attachment to things means happiness.

Society's standards are second hand standards; and yes, this is consistently understood in various other philosophies as well.

Perhaps, the media and all these advertisements that manipulate the minds of people are to be blamed, or the consumers who are just easily manipulated. The corporations advertised to the people in the untainted parts of the world that they need more, and the result is the destruction of nature. Don't even blame the lack of education, people have been uneducated long time ago. Back in the days, people used to be content with the air they breathed and the food they ate. Stop and think if there's a need to feel better by having more and by living in these so-called happiest countries. I've seen the quality of laughter and genuine happiness of the people in my travel experience in these so-called less-privileged countries.

People have/are undergoing "education" more than ever. Goes to show what passes as education nowadays.Perhaps, these people in "less-privileged" countries are more unlearned essentially, meaning they're not as brainwashed.

Do more possessions really improve and add value to our lives?

You already know...awesome post.
