According to these definitions, lower middle class. My dad doesn´t have a college degree, just high school but has a fine but rather typical white collar job (a buyer for a furniture company). I don't know how much he earns, nor do I care, since I have to pay almost everything I want myself. Every piece of hardware I have is 100% earned by me, the bulk of my games is bought by me (some given for Christmas, but they were always a shared gift with my brother), the clothes I wear (except underwear) is bought by me (I have a small allowance of 40 euro's a month to buy clothes, but that's never enough) and I have to pay college myself (together with state support) and I even manage to put some money aside on a savings account every month.
Yea I'm quite happy with my situation, sure I don't get a lot, but it's satisfying to know that that 32" Full HD LCD tv is 100% earned by myself, and that the family only has a shitty, old CRT tv, and that their computer is an old and rotten monstrosity while I have a high tech gaming machine. Thus, I couldn't care less about the class I'm born in.
