The monetary system is what created the world as we know it. It made a simple way to measure how much wealth you have in comparison to other. The idea of having more than the other, greed fueled by self interest.
I wouldn't have it any other way
Value is all subjective, 1 million dollar worth a lot for average household but almost nothing for bankers. You don't care about spending 1 dollar more on your dinner tips, but for some other people that might be one day's pay. And the funny thing is: Those who get lowest salary work the hardest, while those earning millions of dollar per year lying on the beach, just because today's monetary system
This happens because those lying on the beach grab the best part of what those who work the hardest produce. It would be insincere to say that today's monetary system doesn't add up to this, but to say that it is
just because of it would be a little too far-fetched, in my opinion...
Since money can request others' product/services, it is a power. Who get the right to create this power will rule others. Without this power, those who lying on the beach can not request the product of those who working hard, and those who working hard could gain more wealth than former, that is a natural result of energy input
