Helping

helping is perhaps sort of like making something easier for another...

if a doctor helps make a patient well... then he is helping them to get better...

economics and helping
in USA we have dollars which are used to exchange for goods and services....

generally someone is given money if they help someone who is willing to give them money for helping them.

a doctor is supposed to try and help patients be healthy. a patient must pay the doctor for their services.

super-markets give shoppers food in exchange for money.
