Re: suggestion needed 
to correct you, there are fresh graduates from upper middle class and even upper class who are working in Karachi for even less than 20k a month!! And this i am talking about professionally qualified people. in fact it is easier for upper middle and upper class kids to work for peanuts at the start of their career as they don’t really have to worry about the finances or running the house since they belong to well off families. they agree to work for less in order to get into a good well reputed organizations where it is hard to get in and once you are in you get great exposure and opportunities to progress fast.
so if a guy with only bachelors degree working for 20K a month doesn’t imply something fishy.
