Gandhiji revolutionized economics by putting love at the heart of life, where it rightly belongs. Gandhiji said,
"It is my firm belief that it is love that sustains the earth. There only is life where there is love. Life without love is death."
If we find that we live in a society where love has been displaced by self-interest, we can do something about it.
We can love more. With more love we will find life once again invigorated and self-interest will fade away.
