Not all religious people are evil, just like not all ignorant people are evil. But all ignorance and all religion and prejudice and celebrity worship and cults and gambling and extended-cab pickup trucks are certainly evil.
I’m not being pedantic, you’re just wrong. The average income in the US is deceptively high, whereas the median is quite low. This difference (or skew) is a sign of inequality.
The arithmetic mean, also called the average, or the expected value, is not the same type of calculation as the median.
There are many types of means or averages (harmonic, geometric, etc), but they all require a summation, an integral for continuous random variables and sigma notation for discrete. The median is the middle value. Totally different.
