Don't forget that a lot of companies are now going as far as running credit checks on potential employees as well. After all, you're not a true American until you're swimming in debt and desperate to take any meager offering of financial "security". How else would the corporate world ensure financial servitude without resistance? It may not be a big deal at mall outlets and fast food joints, but just about anything beyond is going to frown upon bad credit or even no credit.
Oh, and if you're stupid enough to have any sort of social networking presence listed under you're real name... get rid of it. Create a screen name and operate under a cloak of anonymity, like you should be doing anyway. Lock your profile down completely so that no one can see it from the outside. Or best of all, just don't use social networks at all. Employers, all employers, will do a quick web search on you to find any embarrassing pictures, stories, or even contacts.
Remember that there are always seemingly more qualified people willing to do the same job for less pay. In the current job market, even the smallest thing is enough to get you passed over. Get used to embellishing the truth and overselling yourself if you plan to live at the mercy of others. It's all a game, and it's rigged so that the average person can never win.
