Definately poor with good luck. Start playing the lottery and you are set

Even if you were poor you could go back to school and improve your lifestyle. Now if you were stuck at that level for life, it would be more difficult.
The wife thing isn't super bad. I would be so pissed at her that it wouldn't be super horrible. The parent thing would suck pretty bad, as would not having really any other relatives.
The other side of the coin, it is not possible to be happy with $7,500/yr. You cannot possibly live on that, so you won't be happy. With $12k/yr you could possibly scrape by without a car and still be in a crappy apartment.
