Just like they always said that money is the root of evil that is the real truth about it, because no matter how good someone might be once he or she involves into money their most likely be a changes. Though, that is the main reason why most people normally end up not sticking to their words, more especially the politicians after achieving what they want from the citizens they would lock up an turns their back on people that gave them opportunity due to selfishness and greed. So however, I think is quite obvious right now that whenever there is money between two parties their most likely be a disagreement, because one of them would definitely want to overcome the other just to satisfy their selfish life.
If you want to no some people send them a message to go the market and get a quotation of materials, it doesn't matter the kind of material, what they would do is to get the price and add an amount to every product on the list and when you calculate all the money they have added you will be shocked, so actually money is like a justice of truth because you must learn something from someone if you have money transaction with them. However people should be treated differently when it comes to money because since I have known what people can do about money I usually use wisdom to follow them so that there wouldn't be conflict of money were somebody I will give the total amount to settle workers will use it for themselves.
