credit cards

I applied for a credit card a few days ago and I just found out that I was denied. They said they would send me a reason in the mail. I don't see why they couldn't just write the reason when they wrote that I was denied. So dumb. What they don't realize is that people that don't make a lot of money have more need for a credit card than people who do. I suppose they have some reason why I'm not good enough but that doesn't mean I can't find it stupid. Anyway, that's enough venting. It's not really that important. I just want to be able to establish a good credit rating. I guess I'll just have to keep trying.
