why do people think they are better than others

some pople think they are better than other and it really kinda pisses me off.  I think the reason why people do that is cause some kids have better stuff than others like nice cars and trucks.  Or just really nice toys like dirt bikes or just stuff like that.  Like theres this one kid that went to my school and he had like the nices truck ive seen a kid ever drive and he was real cooky over it.  And he thinks hes so cool cause he has a sweet truck.  But im pretty sure that he mommy or daddy bought him that truck.  Cause he dosent even have a job so he has no way to pay for gas and pay for the truck!! It just makes me mad when people are like that just becaus your daddy baught you that car/truck or anything nice doesnt mean your better than anybody.  So stop think you are if you could stop doing that that would be great thank you have a great day!!!
