Keep in mind that the folks who like it probably aren't going to take to the interwebz to shout their joy from the highest electronic hill; complaints, on the other hand, are apparently fun to share with everyone. Yes, the job market sucks; income potential is better for graduate degree holders than it is folks with a BA/BS. Unfortunately, a Bachelor's degree doesn't carry a lot of weight anymore in the job market.
You especially are in a research-intensive area. If you don't like research, grad school is probably not a good idea for you. OTOH, if you want to go into academia, I'm guessing that's not an issue for you.
A PhD is not a guarantee, so you might want to apply to Master's programs with the understanding that you may have to take out loans to get through the program. Obviously a funded PhD would be better, but that doesn't always happen.
Personally, I like research, and I feel fortunate beyond measure to have been accepted into this PhD program (especially since I was not accepted the first time I applied, and got a Master's degree, instead). But I'm not going to blog about my happiness, either - for starters, I'm too busy with schoolwork, and besides, it seems like gloating.
