Free riders

I am thinking about righting on this topic for quite some time, but was not able to shape in which direction I should write.
Although I am still not very sure what to write, but let start writing .
"Free Riders" in IIMB lingo are people who just sit back and enjoy things while others are doing things to complete projects and presentations. But don't confuse that these people are less competitive or not interested in grades. They are the people who get best returns on their invetsments ( in terms of time). They think about themselves and don't bother about the victims( other persons in their neighbourhood).
This free riding is not limited to studies, it is an allround attitude of these people.
Last line should be " The people who are free riders are free beause others are allowing ".
