A people hire B people.
B people hire C people.
C people hire D people.
D people hire F people.
F people have to hire someone, so they divide their groups into those who can and those who can't. Those who can't become the boot-lickers, those who can become the people who are isolated and told to do the boot-lickers work for them.
That's how I saw what was going on before I left.
In addition, there are no A or B people still working at Oracle. Those are people who expect to be treated fairly and compensated according to the quality of the work they do. A and B people can swim to another ship that is not sinking like Oracle.
