loyalty in life and family

I often wonder why money is more powerful than friendship and will make people betray one another and leave them behind. They will talk to people who they hate and throw others under the bus. All for a buck. I found this to be true in the world of drugs and crime and i am finding that it isnt isolated to the underground and the streets. Betrayl is up as far as the US government and it seems the more money that is at stake, the worse the back stabbing and lies get. Disclosure must happen to fix this. If aliens were common knowledge, 1.] the government would lack the ability to lie and steal from the american people. and 2.] the common citizens would have more interesting things to focus on and money would become less important.
