There are 100 people and all of them want to have a car, home, boat, plane etc. If there is enough of resources and there not going to be damage to the environment then all of them could have their own cars, planes, homes etc. But if the resources are limited and only those strongest, most competitive and most intelligent people can have cars etc. then we will have a system of wealth and poverty.

The most interesting things is that it doesn't have to be this way because if we create a system in which people share these limited resources, than everybody could live in abundance and be able to use the cars, homes, planes etc. without the need to put stress on the environment and letting others to live in poverty while others - most competitive ones - accumulate for themselves more than they need, just out of fear of not having enough in the future ).

Theoretically it is all possible. Practically it is something almost impossible to implement in real life because of the ego, greed and fear of people. But at the same time, there is no other solution and if people don't give up their fear it will all end up in doomsday. There is no other solution so you better wake up before it is too late - Equal Money System.
