Cain slew Abel, not because he was trying to give his thanks to God. He slew Abel because he believed, as one of Adam's two sons, that he deserved to receive God's recognition. When he saw Abel receive God's recognition, but God did not favor him as well, he became enraged. Cain decided he was owed that recognition. He decided that if God was not going to accept his paltry sacrifice as good enough, then he would sacrifice the most precious thing in the world to him. He would "sacrifice" his own brother, and so he committed the first murder.
There's a word in the English language that sums up the reason for everything that I just explained in the previous paragraph. That word is, "entitlement".
According to Merriam-Webster, entitlement means:
1a: the state or condition of being entitled : right
b: a right to benefits specified especially by law or contract
2: belief that one is deserving of or entitled to certain privileges
3: a government program providing benefits to members of a specified group
also: funds supporting or distributed by such a program
Entitlement is the root of all evil, and money is just the modern expression of it.
Conquerors throughout history believed they were entitled to the wealth, riches and land of foreign nations, because they believed their nation was superior to those nations in military terms. Therefore they attacked those nations and took control of that wealth and their peoples.
Bankers believe they are entitled to the wealth, riches and land of all citizens on the planet, because they believe they possess superior intellect compared to the rest of the world. Therefore they tricked the citizens of the world into thinking they were being assisted with their problems, while instead these bankers created a new, subtle form of slavery that never existed before, and took control of that wealth and the people.
There is only one counter to entitlement, and it requires every man, woman and child to take the struggle of that counter upon his and her self.
The counter is personal responsibility, and personal accountability.
