Money is proof of the lack of trustworthiness of people.
We could live exactly the same lives and not use money at all. When we need bread, we go to the baker and he gives us bread. When the baker needs a car, he goes to the car dealer and gets a car without paying. When the car dealer wants to go on a holiday, he takes a plane and goes to stay in a hotel in another country. All of these things could be possible without any money.
Now, why is this not a realistic scenario? Because of just 1 reason – people’s lack of integrity. Of course, if the above would be reality, a lot of people would start to abuse the possibilities. But if everyone would be an honest and decent human being, money would be unnecessary.
So money may not be the root of all evil, but it certainly is a token of evil.
