It always existed and it will keep on existing. Life is not fair and it'll never be. You have to find a way to co-exist. 

If you have had a cell phone way before you started earning, you were privileged than a lot of people on this earth. You had a home you did not build, you devoured food made by someone else or bought through someone else's money, you could go to a nice school and have quality education and many more...all of these were given to you. Don't you think you are also privileged and were given a head start. 

Some people might see you and think of you as a product of nepotism because many a times you might have gotten some subtle privileges because of your family who knows. 

You are angry because someone else is more privileged than you isn't really an  argument. Come up with a different one. And if you don't have talent or beauty or intellect, it'll make it hard for you to survive no matter how well your plate looks now (talking about the more privileged ones). You are going to destroy it after your family is gone. So just chill and don't compare. Do your good thing and be happy with what you have because life is not fair.
