The modern way of thinking about economics has been
I = M - S
Where I is the I as in me, M is what is 'mine' and S is what is shared.
So we are brought up to think that we are what we have , what is ours (M) minus what is shared (S). Sharing in that formulation takes away from me (I).
Gandhian economics suggests that we reverse this usual formulation to read
I = S - M
I am what is shared (S) and what is 'mine' (M) takes away from what I am (I).
Wealth consists in our interrelationships. The greater and more wonderful our interrelationships the greater and more wonderfully do we share, enriching the 'I'.
