At the present moment we know very well that a few men look upon other women, besides one's married wife as mothers; very few men will look upon other's wealth as pebbles on the street and very few men will try to behave with other living beings as one wants to be treated oneself.
The sages of old age discovered it by spiritual culture that man's energy should be utilized only for spiritual realization. Not to speak of Lord Sri Krishna who spoke the philosophy of Bhagavad-gita near about 5000 years ago, we know that within 2000 years of human history no sages including Jesus Christ, prophet Mohammed, Lord Buddha, Acarya Sankara, Madhya, Ramanuja or even Lord Caitanya gave any importance to materialistic way of living. Material necessities were always subordinate to the spiritual realization. They saw it that the bread problem, clothing problem and shelter problem are never solved by material activities because in the law of nature the elephant is given the whole jungle to eat and the little ant is given a grain of sugar to solve their respective bread problems and yet the animals remain hungry. It is not the question of a jungle or a grain of sugar that can solve our bread problem but it is the question of real food that can quench the hunger of human being and revitalise him to proper life. Human being therefore should not be encouraged to satisfy his unsatiated hunger like the giant elephant or the little ant but he should be trained up otherwise which shall provide for his real food.
