What you have experienced is real human nature.It is the time the world of humanity took the next step to the world full of abundance. We need to get rid of the scarcity mentality that has been embedded over centuries of exploitation by the powerful driven by the scarcity/hoarding mentality.
There are many great efforts being done by random people in far off places by reducing their belongings and possessions. Less is more is a concept promoted by a few TED talks.
Human botherhood has been epoused by most of the ancient scriptures all over the globe.Science and technology are now so advanced that the needs of 10 billion can be taken care of as long as there is no exploitation.
