Just want to throw my two cents in, even though I'm sure that what I'm about to say has already been said. Hooray for skimming!
Anyway, there are several things wrong with the mentality you have. Hear me out here, don't just dismiss me thinking that I've already dismissed you. It's a common mistake most people around our age make (21 here) in thinking that a degree is either completely worthless or the end-all-be-all. It is neither. Degrees are worthless because everyone has one. This goes doubly for people in high-demand fields or people who have "fun/dream" degrees (liberal arts, philosophy, acting, etc; things that don't have a direct impact on improving society, as opposed to medicine, engineering, etc), everyone already has a degree. What a lot of people don't have is experience in anything at this point.
What I'd recommend to you is go find a job that has nothing to do with your field. Go work in food service, or tech support, or something with the absolute bitchiest customers you can find. Now hold this job for at least a year. And no bouncing, every time you get a new job, you double how long you have to stay there before the damage from leaving your old job is done. You see, with 3 years of McDonald's experience under my belt, employers in the tech business know that I can deal with the worst of both customers and management, and that I'm able to stick with the job and put in a lot of hard work. All of these are ideal qualities in any employee, and being able to prove with work history, ANY work history, that you have them will do more for getting you a job than your degree could ever hope to.
All that being said, however, don't discount your degree completely. While you need the experience and blah blah blah, before you can enter ANY field, you need to prove that you have learned the basics to doing your job. Any degree you can get shows that you've learned some basic knowledge, and the more specific and related to the desired career you can get, the better. Also the higher the degree, the better. I see you said you're 20? Associates' degrees have never been worth the paper they've been printed on, you need to pursue a Bachelor's or Master's before you can get anywhere. Or, as has been said many times before, go to a trade school. Get something so ridiculously specific, that you'll be a sure-in for whatever career you want.
Now, for a general feel of things, not just education/job related...
Please understand that these economic times happen. Most people our age can't remember all that well, but the DotCom bubble bursting at the turn of the millennium was seen at the time as an incredibly devastating event that we would never be able to recover from. And, despite the terrible economy, the stock market is either close to or already setting new records again. People see what they want to see. Right now you want to see desolation and you're the victim, but that's not really the case.
Let's keep things in perspective. We'll use the Republican's pessimistic numbers and say that 18% of Americans are un- or under-employed. That means that you walk by 5 people on the street, 4 of them are gainfully employed. That's still a massive overwhelming majority of Americans employed at this time. Just remember, you have to have something to offer, a slip of paper is the bare-minimum for entry these days.
Also bear in mind that the young have always been shafted before. Not even a century ago it would have been a miracle for you to have even lived as long as you have. And without a lifetime's experience, you don't know what it's really like to be shafted terribly, so even minor things tend to get to you. You also haven't had the opportunity to see the cycles that this takes, so this one downturn, the only one you remember, is the worst thing you've ever known.
So chin up, get out there, and make something of yourself. After all, a rolling stone gathers no moss; a moving person gathers no cobwebs; any other way you want to look at it. The only way to make something of yourself is to get out there and do it. Sitting, whining, and complaining has never done anything for anybody. All the great leaders and heroes of the world got there by hard work, determination, and admittedly a little luck. But none of them got anywhere by sitting on their asses saying "woe is me".
