People feel undervalued and feel they are entitled to undervalue others, as in employment settings where a person feels their pay is low and use it as an excuse to undervalue their employers and customers. The problem with this is that "values" are externalized. When a person feels the right to be rude to others because of only making Minimum Wage, for example, does that make this person inferior to someone who disrespects them by paying Minimum Wage? Giving or receiving Minimum Wage is besides the point of respect. RESPECT is an INSIDE job.
