Is college degree worth it?

Ok this is probably the most controversial question after high school. I am a 22yr old high school graduate who was in community college but was forced to drop out. I was going for a LPN(nurse). Now to me an Associates degree in Nursing is like a four year degree in another field. Of coarse a takes four years and is higher than an Associates degree but this particular field is not easy as it sounds. Now I am only going for nursing because in my area this is probably the most demanding job with a decent salary. Sure there is nasty stuff you have to look at, snobby nurses and doctors, long back breaking work, and "know it alls'. I was a STNA in the past. The problem is I don't know if I really want to go any further into this. I have a mental block on "at will employment". What this means is your boss can fire you for any or no reason as long as it doesn't violate public policy(discrimination, jury duty, family leave, etc.) At my very first job I was fired by a new manager. Everything was going good until see came there. I just cannot work one job. What if I had a family. Some idiot fires you because they don't like you(not your work) they just have some personal problem with you. I want to become a manager so I won't have to deal with this. The worst thing in the world is having a boss who doesn't know what they're doing and having to listen to them. Anyway when I told my uncle that I was going to school he said "them kids go to school and don't even get them jobs. Get you a trade then you can work for yourself". At first I thought it was because I am a black male and that I could not compete in todays job market. And I know that you just don't go to school, get the degree, and get the job. You have to network, volunteer, be able to write a resume, participate in interships, etc. There is alot of competition and when you get the job you might have satan as your boss. Oh and let's not forget about all those loans you will be paying back. Then I looked into electrical engineering. I can't picture someone paying me $80,000 a year. I would have to get a degree in that and join the military for experience and get another degree in math and all this crap just to be able to compete. Then I have people say that some degree are worthless like some associates degrees. The reality is up here most people make no more than $20 an hour. Colleges throw around these big figures and students believe them. So my question is what is a go field to study? I would be happy making $40,000 a year. What are some nice laid back jobs?
