Answer:
In a choir, there are always people who seem to be given more favor than the others. Those people tend to get solos, they tend to be more respected, and they are the 'well-known' people of the choir. The conductor usually likes these people. Those people are the upper-class, usually seen as the 'top dogs'. Often, there are people who participate in the choir but aren't favorites, and love what they do anyway. Those resemble people like teachers, artists, etc. that do their jobs even though they don't pay great wages, just so they can do what they love. There are also people who need to do what they do (such as people who were roped into joining the choir) so that they can make money. Those people are often seen unfavorably because whatever they do, they may not have a natural aptitude for it. These are the people who grew up in bad circumstances, such as not having access to a good house or proper schooling.
