Im 26yo, unemployed, live at parents house, cant find job, what to do?

My situation seriously sucks, sometimes I just want to cry because I feel like a total failure. So my story is that I graduated from highschool in 2002, I went straight to college at 17yo, graduated with a B.A. in Economics with a double minor in Finance and Managment Information Systems at the age of 22. I moved back home at about 23yo, landed a temp job at a big corporation, then the temp job ended. Since early 2008 I have been unemployed, Ive applied to hundreds of places, if not thousands.

I have crappy communication skills, well not really, Im just introverted so I dont talk as much as employers may like. It seems that to be worthy in this market you must have a certain type of personality, and thats just not me. Since 2008 I have continued going to school, in fact after I graduated I never stopped going, and I have about 3 additional A.S. degrees on top of my B.A. in different fields, Art/Electronics Engineering/and Physics so about 300 total college units, this doesnt seem to have helped my chances at employment either.

I have applied at Target, at Dineyland, at corporate level jobs, Michaels art supply, as a janitor, as a electronics assembler, just so many ENTRY ENTRY level positions. Either I dont get called back, Target/Michaels/janitor/assembler/and countless other jobs, or I get called back, Disneyland, and I mess up the interview because Im not as outgoing as that 18yo highscool dropout. I seriously lose jobs to highschool kids, which is sad.

I feel that corporate america gives jobs to the stupidest people out there, I know of two people in particular, both never finished highschool, 1 is the Vice President of a large corporation, he makes $500k a year and I know him personally, hes not very bright, BUT HES A SMOOTH TALKER. Another person I know, also a highschool failure, stole almost 100k from a company, she lies and says she has a B.S. in Accounting, she has problems remembering her times tables, and she gets jobs ALL THE TIME, starting pay $50k, shes not very bright either, BUT A SMOOTH TALKER.

w*f is wrong with America, is this how we reward college gradautes, by handing out jobs to idiots instead of them. I seriously feel that corporations need to have their hiring process taken over by the government so that decent hardworking people can get jobs TO LIVE. They either tell me I dont have enough experience or that Im overqualified, w*f do you mean overqualified, the word qualified is in there, so hire me.

So back in the laboratory aty parents house, I sit at home while idiots get hired left and right, I cant even get a job at grocery stores, you know why, because here will come little miss airhead with 10yrs of experience under her belt. Then they will compare me and her, say, well she has experience, ALL HE HAS IS AN EDUCATION, ERRRR, lets hire the airhead. EXPERIENCE IS BULLSHIT...unless you are an engineer or in some VERY technical field, experience is worthless and teaches you only a small portion of what a college graduate learns.

Im VERY intelligent and I feel thats its a waste of my brain to not be able to do anything with it. I do work on my own inventions and gadgets all the time, but I just dont have the money to do anything great with my brain. Also, Im an AMAZING ARTIST, I have no doubt that when Im dead my art will become famous and be worth lots of money, but in the meantime I am a failure, because I gradauted at the wrong time, and grew up with the wrong personality and grew up in a world where stupidity is admired.

Can somebody, please give me some advice, Im tired of living at home, of not being able to move on with my life or find a mate because Im a loser, Ive considered suicide many times, and have even considered living in the street and just being homeless. What makes me even more upset is that I come from a family with money, and they know how sad I am about my situation, yet they dont try to invest in me or my ideas, Im not asking for a handout, but If my own family doesnt believe in me...why should someone else.

I seriously dont have any faith in Americas future, AT ALL.
