To think something is mediocre is to think that it is not the extraordinary giving an experience we are after or wonderfully surprised by. Mediocre is something most people like to avoid belonging to, being called and having it. Why is mediocre the dull and average way of life, choosing a life and a mode on to which mainstream is build and is still so much loathed as something unwanted and boring but still liked and wanted? Those boring characteristics usually are repetitious and given from above to avoid thinking for yourself, to avoid conflict and find alternatives that might be somewhat different and contradicting to power relations, taste, traditions and common ways of thinking which feel safe, good and acceptable.
Mediocre is the acceptable something we fall for because it is something we all should be having, enjoying and doing and we like this bond. For instance owning certain electronic devices is seen normal and they belong to modern home which we all share. The fact that electronic tools making our lives easier are at reach for all is making the mediocre mode we now know as normal accessible in a way that we do not have to question these choices which we make to fit in to be connected. We want to be part of the world that lives via electricity and labor forces of far away lands. Cheapness is mediocre but it can be expensive. We do not question because we do not have to, our comfort is a state of peace of mind but also state of selfish demand to fulfill all needs which mediocre people want because they reach out for the perfect comfort and ease, but also perfect level of luxury with which to compete and compare. Mediocre is one kind of battle and competition between those who like material good and appreciate status this visible wealth bring.
