Why do people value themselves so low?

i just got through watching the health documentaries food incorporated and supersize me and learned that our youth population is just being blinded when i look at our civilization say for instance a grocery store i see that at least 75% of that store were at least overweight and about 15% obese and guess what the cause was....... fast food companies!! its these frigging retards that are blinding people and tricking them into thinking that their food is actually healthy! i absolutely cannot fathom this and (im a certain age that i cannot disclose because i know there are lots of hackers on the internet that only need a couple things and will be at ur house in minutes to kill u according 2 my mom)im around the tween teen age lets leave it at that. i cannot fathom that all these years ive been eating garbage that has been processed like 2 billion times and indulged with growth hormones that have names as long as 28 letters! this country is unbelievable (U.S.A.) its true that its the country that has the biggest everything but here is what i think is tearing our country apart on a list 1.obesity i have already talked about this and there are many reasons such as fast food being the source of cancer and heart attacks and ppl are lying in their deathbed asking why am i dying i didn't do any thing unhealthy i might have a few extra pounds and it turns out that they eat mcdonalds evry day with all this fat plus fast food really affects ur brain so if ur the underdog in ur class and u eat no breakfast or eat fastfood alot then guess what NEWSFLASH!! u finally know whats wrong and guess what all the homeless population did not just come out of nowhere now im not an expert at this but my hypothesis is that the homeless population came when these mc whatevers came and im just as guilty as anybody and im trying to get rid of the garbage personally and who would like to eat a meat pattie that u think came from one cow and there are no diseases from all these condiments and hamburgers guess what that pattie contains a billion kinds of cancer and billions of cows yet we are cutting down the rainforest to have room for this poor mass produced species which probably has the cure to cancer because the forest has all kinds of uncharted plants but maybe the cure to cancer is to stop eating it hmm... does that idea intrigue you world? well it should maybe if we stop eating the presently incurable disease that disease would probably go away our homeless pop. would go down as heck. now that ive wasted more than 2000 letters on my complaints on fast food let me spend some on something else 2.drugs drugs are a worthless and harmful thing that make you a drop out for sure and therefore add to our bad reputation and our homeless population and all it does is let the emos feel good and high for a few seconds and why are they emo? guess what america fast food+human= low self esteem the clueless fat people are looking at us skinny people thinking dang i wish i could be one of them and then they think that they can be in control of the pain by cutting themselves and gettin high therefore again does this ring a bell adds to bad reputation and the homeless population big surprise!! and in the movie the guy was actually having a really low self esteem from mcdonalds now im gonna have 2 cut this short and start abbreviating cuz im low on words dont judge me for my use of language now its gonna get slangy 3. pregnant teenagers do you know what country has the highest abortion rate guess who the U.S.! we have so many teen pregnancy guess what for highschool and middleschool kids are thinking that "oh i can get a guy to love me by giving him my body and all that crap and then they end up in the emergency room a couple months later on an opera. table with their parents looking at them in utter disappointment it is so sad all that just to get a guy to love you and then if the baby is born guess what he moves to kalamazoo just to get away from you all that just to have a little bit of fun time that is not even worth it (i understand because im falling into that pervy stage of life right now) so i gotta wrap this section up too 4.smoking this will be short why do we always have to smoke seriously what good comes out of it to the user it might taste good and nothing else the bad is that it totally screws up ur lungs and then u get lung canc., it smells terrible to us other people and it shortens your life like heck plus it adds to the bad reputation we got goin on 5.smart people like myself i cannot fathom that this country barely has any critical thinkers you do not go down the street and survey ppl you do not ever see any one who is the future billgates type say if you interview some one what job they have i bet none of the kids and such would say "i wanna be a programmer when i grow up" this is a coincidence but this suits me) so and also get rid of rap it intros bad values too so go answer and tell me what you think and if u
