Well, half of the population has an IQ of less than 100. Also, if everyone tries to achieve greater education, then what's considered "upper middle" will shift.

Well, half of the population has an IQ of less than 100. Also, if everyone tries to achieve greater education, then what's considered "upper middle" will shift. Just look at the devaluation of associates and bachelors degrees today. The sad truth is that there will always be lower and lower-middle class jobs, because not everyone is capable of joining the upper-middle class. Should those people continue to experience a declining quality of life just because they haven't been genetically or socioeconomically blessed?
