I need a job desperately, please help me???!!?

okay so obama got elected last year for president and ever since then weren't more people supposed to get employed? cus i haven't seen a single change with the economy ever since obama got elected, in fact its gotten worse. Well here's my situation, i'm 17 years old, live at home with a single mother( my dad ped away) 2 sisters, one 20 and the other 13 and a baby 2 year old baby brother. My 20 year old sister doesn'y have any job experience because she isn't that smart, not cus of slackin of at school or anythin but because she had trouble learnin, its some type of disorder but i dont know wat its called, my mom doesn't have much education so she work full time jobs at places where teens usually go lookin for jobs at (McD's, BK, etc) and she is currently workin at this gas station as a cook, she might loose her job tomorrow because the manager and the other cook steal from the store and since they noticed that my mom doesn't say much they figured she might rat em out so they started givin her a hard time at work until my mom finally snapped and told them she wasn't gonn ado wat they asked (wat they asked from her was things she wasn't hired to do and that theyw ere supposed to do but just cus they're lazy they made her d them) so yeah she might loose her job, i think tomorrow they are gonna speak with the one person who is in charge of the gas station around the area where i live, now to me, i have applied at many fast food places and the closest i got to a job was an interview but nothin after that, no call no nothin, at a BK as soon as i turned in the app the manager told me she was gonna call me in 2 days but she never did, so i went the day after she was supposed to call me to see wat was up and they said that they weren't hiring, at this place caled Stars ( a drive in fast food like In and Out, Sonic, etc) the manager asked me if i was willin to work as a cook and i said sure and she never calledm so i did the same as i did wit BK and she said sorry that business was slow....to top it all of i got no job experience at all so i think that just lessens my chances, and here where i live the whenever at school that so and so got hired i find out that its cus they got a family member that hooked them up, wat is goin o with this world!! my family is about to lose our home and we are only livin of food stamps and some money that we recieve from my father's death from the gov, but its not enough and i just want a simple job, heck 10 hourse a week would be enough for me as long as i can help out at home in any little way!!!!!!!
