Why does everyone make fun of the young teens asking about fast food jobs in this section?

I mean honestly you guys couldn't be more wrong. Some poor teenager comes in here asking about how to get a job at mcdonalds and you say some snide remark like "make sure you are a middle school drop out" I worked at Dairy Queen and Pizza Hut in high school before I went to college just as temporary jobs and now I own my own law firm and I make over 250k a year. Most people start at the bottom and I think people in this section should be more respectable to these kids especially since they actually WANT to work unlike a lot of losers on here. Sorry this seems like a rant but what makes people look down on someone who's a fast food worker opposed to someone who works at lets say best buy and makes the same amount of money? It seems like people always say "working at mcdonalds the rest of your life" whats so much better at working at a store in the mall or a restaurant like outback steakhouse for the rest of your life?
