So you fuck up , get convicted , and now you have a black mark on your record . You do your time and get out , your gonna do it right this time , you learned your lesson . First thing you do is try and find a job , you don ' t have many marketable skills , that ' s why you were selling drugs in the first place , so your stuck with low paying jobs like McDonalds or some other fast food joint . But your at the very end of the hiring list because your background check comes back with a felony , so your gonna struggle to even get a shit job , but you keep on keeping on and you finally get a call back from Burger King and you get the job , great now you can start paying your sister back for letting you stay and save up some cash for your own place . Well , good luck getting an apartment , your a dirty felon and most places don ' t want your kind in their apartment building where they actually fix the leaky roofs and make sure the heat works in the winter so your gonna have to live in the run down apartment building ran by some guy who only seems to understand English when it comes time to collect rent . Oh , and since this is the only place in town that accepts felons as tenants , it ' s full of felons some of which may or may not be trying to do good this time . So your surrounded by the same environment that got you in trouble in the first place . So your poor , living in a rat ' s nest , and surrounded by the same shit you tried to get out of , it ' s not hard to see why maybe they would start thinking about slinging dope on the side to make little extra money .
