A person who is limited with options and he/she can’t question against authority. For example: a poor man cannot question the orders of his rich master.
The major barrier that encompasses all these types of barriers is that of racism. White people have an authority bias against the colored race. They would be under a halo effect and by the extreme amount of peer pressure follow what is being followed in the society around them resulting in oppression of colored people. This could be in terms of workplace oppression, education opportunities and verbal/physical abuse (Brookfield, 2011).
