LOL if the job market is so bad and the economy is in the shitter how many companies do you think actually do those background checks? That shit costs money, if it ain't a job for the government or a big corperation i'd just chance it and lie, worst thing that could happen is you dont get the job. I'd just go to the interview not dressed like a felon, shave the shit off your face and put your best foot forward. Most companies skimp on that kind of shit.
besides that you can get your CDLs and drive trucks, my best friend has a couple felonies and he drives concrete and does pretty well for himself.
Half my friends from highschool have been to the joint at least once and most of em do alright doing construction and shit. Its all about the skills you have and how you sell yourself. I'd never tell a company that I ever committed any crime period unless its a government gig where i know they will check.
